State cercando di correggere l’errore 404 della sitemap di Yoast SEO in WordPress?

Yoast SEO è uno dei plugin SEO più popolari per WordPress. A causa di un conflitto tra i plugin o di impostazioni errate di WordPress, potrebbe mostrare un errore 404 quando si cerca di visitare la sitemap XML.

In questo articolo vi mostreremo come correggere facilmente l’errore 404 della sitemap XML di Yoast SEO in WordPress.

Fixing Yoast SEO XML sitemap 404 error in WordPress

Cosa causa l’errore 404 di Yoast SEO Sitemap in WordPress?

La sitemap di Yoast SEO aiuta i motori di ricerca a trovare tutti i contenuti del vostro sito web che volete che trovino e indicizzino.

Correggendo l’errore si garantisce che i motori di ricerca possano accedere alla sitemap e scoprire tutte le pagine e i contenuti del sito, il che può portare a una migliore visibilità e posizionamento sui motori di ricerca. Questo aiuterà anche a classificare i contenuti più velocemente rispetto a quanto avviene senza una sitemap.

WordPress viene fornito con una sitemap XML predefinita da inviare a Google Search Console e ad altri motori di ricerca.

La sitemap XML può essere visitata inserendo il seguente URL nella barra degli indirizzi del browser.

https://example.com/sitemap.xml

Tuttavia, la sitemap predefinita generata da WordPress è molto semplice. Per correggere questo problema, tutti i plugin SEO WordPress in alto, come All in One SEO for WordPress o il plugin Yoast SEO, creano le proprie sitemap XML con più caratteristiche.

Quando si utilizza la sitemap XML generata dal plugin WordPress SEO, questi plugin riscrivono lo scorciatoia predefinita di WordPress XML sitemap.

Ciò significa che l’URL della sitemap di cui sopra invierà gli utenti alla sitemap generata dal plugin SEO di WordPress.

Purtroppo, questo può causare un errore 404 su alcuni siti web a causa di conflitti tra plugin o impostazioni errate di WordPress.

Detto questo, vediamo come correggere facilmente l’errore 404 della sitemap di WordPress nel plugin Yoast SEO.

1. Ricarica della struttura dei Permalink di WordPress

WordPress è dotato di una struttura di URL orientata alla SEO (chiamata anche permalink). Questa struttura di URL utilizza un sistema di reindirizzamento per indicare al server di hosting web quale pagina caricare quando un utente inserisce un URL nel browser.

Di norma, le impostazioni dei permalink vengono aggiornate automaticamente quando si apportano modifiche al sito web.

Tuttavia, a volte WordPress potrebbe non essere in grado di ricaricare la struttura dei permalink, causando la comparsa dell’errore 404 della sitemap di Yoast SEO.

Questo problema può essere facilmente corretto visitando la pagina Impostazioni ” Permalinks nell’area di amministrazione di WordPress e facendo clic sul pulsante “Salva modifiche”.

Update permalinks

In questo modo si ricaricano le impostazioni dei permalink di WordPress. Ora è possibile visitare la pagina della sitemap XML per verificare se il problema è stato corretto.

Se il problema non è stato corretto, potete continuare a leggere.

2. Aggiornamento manuale dei permalink

Se la ricarica della struttura dei permalink di WordPress non corregge l’errore 404, è possibile indicare manualmente al server web di reindirizzare gli utenti alla pagina della sitemap di Yoast SEO.

A tal fine, è necessario aggiungere il seguente codice al file .htaccess.

# Yoast SEO - XML Sitemap Rewrite Fix
RewriteEngine On
RewriteBase /
RewriteRule ^sitemap_index.xml$ /index.php?sitemap=1 [L]
RewriteRule ^locations.kml$ /index.php?sitemap=wpseo_local_kml [L]
RewriteRule ^geo_sitemap.xml$ /index.php?sitemap=geo [L]
RewriteRule ^([^/]+?)-sitemap([0-9]+)?.xml$ /index.php?sitemap=$1&sitemap_n=$2 [L]
RewriteRule ^([a-z]+)?-?sitemap.xsl$ /index.php?yoast-sitemap-xsl=$1 [L]
# END Yoast SEO - XML Sitemap Rewrite Fix

Nota: se il vostro sito web WordPress è installato in una sottodirectory o cartella (ad esempio https://example.com/mywebsite/ ), dovrete utilizzare il seguente codice.

# Yoast SEO - XML Sitemap Rewrite Fix
RewriteEngine On
RewriteBase /mywebsite/
RewriteRule ^sitemap_index.xml$ /index.php?sitemap=1 [L]
RewriteRule ^locations.kml$ /index.php?sitemap=wpseo_local_kml [L]
RewriteRule ^geo_sitemap.xml$ /index.php?sitemap=geo [L]
RewriteRule ^([^/]+?)-sitemap([0-9]+)?.xml$ /index.php?sitemap=$1&sitemap_n=$2 [L]
RewriteRule ^([a-z]+)?-?sitemap.xsl$ /index.php?yoast-sitemap-xsl=$1 [L]
# END Yoast SEO - XML Sitemap Rewrite Fix

Non dimenticate di sostituire /mywebsite/ con il nome della vostra sottodirectory.

Questo codice indica semplicemente al vostro server quali pagine visualizzare quando gli utenti accedono alle sitemap XML di Yoast SEO.

Ora si può provare a visualizzare la sitemap XML per vedere se il problema si corregge.

3. Passare a un plugin XML Sitemaps

Se i metodi sopra descritti non hanno risolto l’errore 404 sulla pagina della sitemap XML di Yoast SEO, si può provare a utilizzare un plugin separato per generare sitemap XML per il sito web.

Lo svantaggio di questo approccio è che dovrete affidarvi a un plugin separato per generare sitemap XML e a Yoast SEO per altre caratteristiche SEO.

Per prima cosa, è necessario installare e attivare il plugin XML Sitemaps. Per maggiori dettagli, consultate la nostra guida passo-passo su come installare un plugin di WordPress.

Dato che si utilizza Yoast SEO, verrà mostrata automaticamente una notifica per disabilitare il plugin XML Sitemaps o la funzionalità sitemap di Yoast SEO.

Yoast SEO XML Sitemap conflict warning

Fare clic sul pulsante Attiva/disattiva la Sitemap XML di Yoast SEO per continuare.

Si accede così alla scheda Caratteristiche della pagina SEO ” Generale”. Da qui è necessario scorrere verso il basso fino all’opzione XML Sitemaps e disattivarla.

Disabling XML sitemaps in Yoast SEO

Non dimenticate di fare clic sul pulsante “Salva modifiche” per salvare le impostazioni.

Ora è possibile passare alla pagina Impostazioni ” XML-Sitemap per configurare le sitemap. Per la maggior parte dei siti web, le impostazioni predefinite funzionano subito.

XML Sitemaps settings

Ma è sempre possibile configurare le impostazioni in base alle proprie esigenze.

Ora è possibile inviare l’URL della sitemap XML alla Search Console di Google e ad altri motori di ricerca.

Sitemap URL

4. Passare a Tutto-in-uno SEO per WordPress

Se tutti i passaggi per la risoluzione dei problemi falliscono e non si desidera utilizzare un plugin separato per generare sitemap XML, questo metodo può aiutare a correggere l’errore 404 della sitemap.

Per questo metodo, avrete bisogno di All in One SEO per WordPress. Si tratta del miglior plugin SEO per WordPress presente sul mercato e di un’alternativa molto migliore a Yoast SEO.

Per maggiori dettagli sulle differenze, potete consultare il nostro confronto Yoast vs All in One SEO.

All in One SEO (AIOSEO) è dotato di sitemap XML avanzate con opzioni facili da gestire che consentono di avere il pieno controllo su cosa includere o escludere dalle sitemap XML.

Per prima cosa, è necessario installare e attivare il plugin All in One SEO for WordPress. Per maggiori dettagli, consultate la nostra guida passo-passo su come installare un plugin per WordPress.

Nota: esiste anche una versione gratuita di All in One SEO per WordPress, che include la maggior parte delle caratteristiche delle sitemap XML, ad eccezione di quelle relative a video e notizie.

Dopo l’attivazione, il plugin vi guiderà attraverso una configurazione guidata. Se avete bisogno di aiuto durante la configurazione, potete seguire la nostra guida su come configurare correttamente il plugin All in One SEO per WordPress.

All in One SEO setup

All in One SEO vi permetterà anche di importare i dati SEO da Yoast SEO.

Questo assicura che tutti i meta tag e i titoli SEO precedenti rimangano invariati.

Import Yoast SEO data

Dopo la configurazione iniziale, si può andare alla pagina All in One SEO ” Sitemaps per configurare le impostazioni della sitemap XML.

All in One SEO sitemaps settings

Fate clic sul pulsante Apri Sitemap per verificare se è stato corretto l’errore 404 della sitemap di WordPress.

Successivamente, si configurano le impostazioni della sitemap, se necessario.

Per esempio, All in One SEO consente di scegliere cosa includere nelle sitemap. È possibile aggiungere o rimuovere post type, tassonomie, singoli articoli e pagine.

All in One SEO sitemaps advanced settings

Tutto-in-uno SEO permette anche di creare video, notizie, sitemap RSS e sitemap HTML per il vostro sito web.

Additional sitemaps

Queste sitemap possono anche essere inviate a Google Search Console e ad altri motori di ricerca. Questo aiuta i motori di ricerca a trovare rapidamente i nuovi contenuti del sito web.

    I just bought the Genesis Framework theme and then installed the yoast seo plugin and activated. I then tried to generate my sitmap and get this same 404 error.

    “Not found, error 404
    The page you are looking for no longer exists. Perhaps you can return back to the site’s homepage and see if you can find what you are looking for. Or, you can try finding it by using the search form below.”

    Does this mean that the theme I got from Genesis is badly coded? Did I waste my money??

      • Chris Sparks says

        I had a similar issue after installing Yoast SEO. I deactivated the plugin, then restarted and the URL system picked up and started working as expected. This seems to be related to how the permalink structure is set up as only one of our sites has experienced this issue.

        Thanks for posting!

  3. john says

    hello I tried fixing the 404 error code and now I get the following messege:

    Internal Server Error

    The server encountered an internal error or misconfiguration and was unable to complete your request.

    and after that i remove the folder of plugin seo and nothing is working again what can i do???

  4. Eoin Healy says

    Another easy way to fix the sitemaps is to simply disable sitemap functionality and enable it again…. works for me every time, doesn’t matter what plugins i have installed.

    In Admin, to go SEO > XML SItemaps
    Under ‘XML Sitemap’ uncheck ‘Check this box to enable XML sitemap functionality.’, hit save, check the box again and hit save.

  5. Margot Barrios says

    I already fixed using the first option, how would I know if it’s working already? Should I need to wait for Google’s webmaster report? This is where I saw the 404 error on my site.

  6. Eric Kuhn says

    I replaced the edit files with the XML sitemap fix and completely removed what was there initially. Google webmaster tools has accepted the sitemap however, my sitemap doesn’t show a 404 or anything. Does that mean everything is ok?

  7. Melissa says

    I tried fixing the 404 error code and now I get the following messege:

    Internal Server Error

    The server encountered an internal error or misconfiguration and was unable to complete your request.

    Please contact the server administrator, and inform them of the time the error occurred, and anything you might have done that may have caused the error.

    More information about this error may be available in the server error log.

    Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

    Apache/2.2.23 (Unix) mod_ssl/2.2.23 OpenSSL/1.0.0-fips mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 Server at artattackfx.com Port 80

    I cannot access the WP Admin Site… How can I revert to before I added this code :

    # WordPress SEO – XML Sitemap Rewrite Fix
    2

    3
    RewriteEngine On
    4
    RewriteBase /
    5
    RewriteRule ^sitemap_index\.xml$ /index.php?sitemap=1 [L]
    6
    RewriteRule ^([^/]+?)-sitemap([0-9]+)?\.xml$ /index.php?sitemap=$1&sitemap_n=$2 [L]
    7

    8
    # END WordPress SEO – XML Sitemap Rewrite Fix

    to the htacess code in YOAST? Please Help.

      • Remi says

        I thought I followed to the letter your second suggestion but have the same issue as Melissa. Now waiting for the Webhost for a solution. What about adding a warning in your second solution that it can lead to a 500 Internal Server Error.

        • WPBeginner Support says

          You can also revery back by editing the file your modified through FTP. Connect to your website using an FTP client. Locate the file you modified (.htaccess or class-sitemaps.php) and remove the code you added. Alternately, you can also delete the WordPress SEO folder from your wp-content/plugins/ directory through FTP.

  8. Toni says

    Can anyone advise on how to delete the post-sitemap.xml as I cannot find it in my root directory! I have turned of the generate sitemap in Yoast.

  9. Koen says

    Hi,
    I have wordpress 3.6 with Avada theme and WordPress SEO by Yoast plugin.
    First I got the 404 error page.
    Then I applied the .htaccess fix without any result.
    Then I applied the class-sitemaps.php fix, now the sitemap returns a blank page.
    What to do?
    Please help. Avada isn’t a crappy theme, I think.
    Cheers, Koen

    • Frank says

      Koen,

      I’m having the same problem I was thinking it was a Nginx issue because I’m not hosting on an Apache server.

      are you hosted on a Apache server?

  10. Gbenga Adebayo says

    Hi,

    Appears i still have a few issues to sort out. Google webmaster reporting http 403 errors with my sitemap. I can’t find the sitemap anymore in my root folder. I can navigate to the sitemap using my browser without getting a 404 error message.

    Any suggestions or help is appreciated.

  11. Madhu says

    Phew … Thanks again!
    I updated my SEO pluggin and the sitemaps had the same issue.
    I had to incorporate both the fixes.

  12. Rajesh Thakur says

    Thanks First one did worked for me need to clear w3 cache after that and wait a little also disable XML sitemap checkbox and check it again

  13. Erica says

    I tried the second set of instructions and it resulted in a “Fatal Error” message and I was unable to access my WP site, or even the login page. Scary!

  14. Nyla says

    Hi all

    I’m an very frustrated to say that I am too getting 404 error, I’m using kriesi replete theme.

    I have tried both options however nither worked

    I’m not sure if I’m doing it write, can somebody explain…. In simple terms are we deleting and replacing the existing code on both options? Or just adding? It’s not clear or does it make a difference if the prexisting remains

    Thanks in advance

  15. Rohin says

    Damn helpful.
    One of my clients had this problem and just took 5 minutes to solve the issue. Just because of this post.
    Thanks a lot.
    :)

  16. Ron MacGregor says

    I am new to WordPress and have only begun a using the Canyon theme. I got the 404 message as I was attempting to install a “contact info” plugin. Does anyone know if I just begin at the very beginning again, i.e. go through my GoDaddy account to reinstall WordPress and then reinstall the Canyon theme – might that solve the 404 problem?

  17. Jack Logan says

    I have two sets of websites (WordPress Multisite installs) and I have no issues with sitemaps on one of them and I get a 404 error with category_sitemap.xml on the other one.

    I tried both fixes suggested in this post, but they don’t solve the issue. The only thing that works is going to Posts -> Categories – Edit and changing from “Auto detect” to “Always include” on all categories.

    The issue here is that I have over 200 sites, and about 8 categories per page, so it would take too long to do it just to get category sitemaps, even though I could use it….

    Is there any way to mass change all the categories on WP Multisite to “Always include”. I think this would be a solution that would work for everyone.

    Thank you.

  18. Jacques Karsten says

    If none of this works try create a file named sitemap_index.xml on your html root through ftp and make sure the permissions are set and the plugin should then take care of the rest.

      • John says

        I did both and it started working. It sounds pretty obvious, but make sure if you copy and paste that you take the line numbers out. I forgot to and broke my .htaccess file for a few minutes.

  19. Hector Torres says

    Hi, just wanted to give my thanks, used the second option suggested ad it fixed my 404 error. Thanks!

  20. Adam says

    I’m not sure which part worked for me, but I found this page because I was getting the 404, too. I disabled the XML Sitemaps in the plugin, then enabled it and checked the boxes to exclude posts (since I only have pages). Now, it is working perfectly.

  21. Brad Dalton says

    I think there are other issues with this plugin as well.

    The attachment pages aren’t all redirecting to the parent page which is something i noticed today.

  22. Michi says

    No other comment since April. That has been 5 months since. I have the 404 still in Sept 2012! Was able to fix it with the .htaccess fix. Thanks for posting
    Just wondering why this is STILL an issue.

  23. Sandie Wright says

    It worked for me! Open the class-sitemaps.php file located in plugins > wordpress-seo > inc folder. then find the code around line 79 and replace the old code with this new code:
    /**
    * Initialize sitemaps. Add sitemap rewrite rules and query var
    */
    function init() {
    global $wp_rewrite;
    $GLOBALS[‘wp’]->add_query_var( ‘sitemap’ );
    $GLOBALS[‘wp’]->add_query_var( ‘sitemap_n’ );
    add_rewrite_rule( ‘sitemap_index\.xml$’, ‘index.php?sitemap=1’, ‘top’ );
    add_rewrite_rule( ‘([^/]+?)-sitemap([0-9]+)?\.xml$’, ‘index.php?sitemap=$matches[1]&sitemap_n=$matches[2]’, ‘top’ );
    $wp_rewrite->flush_rules();
    }
    Then, go back to your WP admin page and then go to the SEO plugin > XML sitemaps, and then click the button again (XML Sitemap). The 404 should be replaced with your sitemaps! Easy peasy.

  24. Jody says

    Thanks for jacking up my site! i tried your code and now i got a 500 internal service error i have been trying for hours to fix! thanks for making my little problem into a HUGE problem!

  25. Eva says

    Hi!

    Thank you so much for posting this article! With the first fix, I managed to solve the 404 issue for most sitemaps, though there’s still 1 that is showing the error… Any suggestions of what to do?

    I thought about exporting the Yoast SEO settings and reinstalling the plugin to see if that does the trick. Just to be on the safe side: does exporting literally export all settings, even the page/article level SEO customizations OR only the general settings?

    Thanks!

    Eva

  26. Sara says

    Thanks so much – this worked for me.

    I know you said the plugin is good, and the problem is in the theme or other plugins, but I tried disabling all plugins and switching to the twenty eleven theme, and the sitemap still gave a 404 error. The only thing that worked for me is editing the htaccess file.

    • Boah says

      … and I tried the same thing. Removed all the plugins, all the themes, and tried it again: 404 error. To make it worse: I’d have an .htaccess file because of IIS. Which options are there for me?

  27. Rusty Solomon says

    I guess SEO Yoast recent update have sitemap problem as I cant see any sitemap on the URL the plugin provide. Let me know if any one has the same issuee and Fix.

    Also is there any good plugin avaialble as same as SEO Yoast.

    Thanks & Regarsd

  28. Jay Wylie says

    Hi, I have tried the first fix, but broke my site in the process. Is there anyway to re-edit my htaccess file, to stop it causing a 500 internal server error?

    thanks

  29. Colin says

    Hi Joots, I’m using the latest version of the SEO plugin. I’m going over previous posts and completeing the various fields, “Focus Keyword”, “SEO Title”, etyc, etc but after I update the post and then go back to “Edit” those fields are then blank again. I wondered how I could rectify this?

    Thanks,

    Colin
    Liverpool, UK

  30. Saki_Kawa says

    The solution doesn’t resolved my issue.. I still have a blank page at post-sitemap.xml
    Does someone have a solution?? Or I need to unistall this plugin and find another one for my sitemap..

  31. Adam Parnala says

    Hi, I don’t have any problems with yoast seo plug in as I’m currently using it. I just I want to ask if it is better than the all in one seo plug in? I’m just curious because I found out that a lot of blogs in my niche uses it. Which is better? the all in one seo or yoast seo? (I’m already used to yoast). Oh, can I also ask how to set multiple focus keyword in Yoast seo? because there is only one field and I can’t figure out how to set a few more keywords for it. Sorry for my questions I hope you can answer me. Thanks!

    • Craig says

      I’d be willing to test a better fix for this issue but I’m reluctant to commit to a timeframe as I’m not really good at keeping on top of my todo’s since my stroke. (This is one of the reasons I haven’t returned to work as a PHP coder yet.)

      And I’d be *very* interested in helping if I happen to be experiencing any of the issues cited above.

      Craig

  32. Stephen Cronin says

    Hmm, I think the second part is going to cause the rewrite rules to be flushed on every page load, which <a href=”http://codex.wordpress.org/Rewrite_API/flush_rules”>the Codex</a> warns not to do due to performance issues:
     
    <blockquote>Because this function can be extremely costly in terms of performance, it should be used as sparingly as possible – such as during activation or deactivation of plugins or themes. Every attempt should be made to avoid using it in hooks that execute on each page load, such as init.</blockquote>
     
    I’m guessing that’s why Joost isn’t doing that by default :)
     
    Of course, I could be wrong because I don’t know his plugin well enough.

    • jonbish says

      I was under the same impression when this article came through my RSS. I’m pretty sure going to your permalinks settings page would accomplish the same thing without having to flush the rewrite rules every time the page loads.

      • yoast says

         @jonbish Unless you’re running a crappy plugin or theme that DOES flush on every pageload before this plugin gets a chance to get its rewrites in.

        • wpbeginner says

           @yoast  @jonbish Yes we understand that this is probably a compatibility issue. Yoast sitemaps work fine on our sites. We had to do this on a client’s site.

        • yoast says

           @wpbeginner  @jonbish I know YOU understand, question is: do your readers :) We’re working on a fix for these kinds of issues in core btw: http://core.trac.wordpress.org/ticket/18450

    • yoast says

      You’re 100% right Stephen. Something else *is* doing it on each pageload, which forces this “fix”, which isn’t a fix but a workaround for a broken theme or other plugin…

    • icejava says

      Its probably not blank, just how your browser renders XML (maybe Chrome, mine does it too). View the source code of the page and you shall see the light ;)

      • Editorial Staff says

        This happens for a few reasons. Either you’re running low on memory. Two the file that generates the visual layout in your /wp-content/ directory is not working properly. Perhaps because you blocked the php execution?
