Recentemente, uno dei nostri lettori ci ha chiesto come cancellare la cache di WordPress.
Il browser web, il server di hosting e i plugin di caching possono tutti servire contenuti memorizzati nella cache, il che può rendere difficile vedere subito le modifiche apportate al sito web.
La cancellazione della cache di WordPress è anche il primo consiglio per la risoluzione dei problemi che si sente spesso.
In questo articolo vi mostreremo come cancellare correttamente la cache di WordPress. In questa guida tratteremo la cache del browser, la cache dell’hosting web e i migliori plugin per la cache di WordPress.
Che cos’è la cache in WordPress?
Le soluzioni di caching memorizzano le versioni statiche del vostro sito web in una cache. Ciò consente a WordPress di non eseguire gli script PHP più pesanti a ogni caricamento del sito.
Il processo di caching contribuisce a migliorare la velocità e le prestazioni di WordPress e l’esperienza complessiva dell’utente.
Ecco un esempio di come si presenta il processo di caching:
Esistono diversi tipi di soluzioni di caching per WordPress. Il metodo più diffuso è l’utilizzo di un plugin per la cache di WordPress, come WP Rocket o WP Super Cache.
Questi plugin consentono di controllare quali file e media vengono memorizzati nella cache, quando la cache scade, quando la cache viene ripulita e altro ancora.
A seconda del vostro provider di hosting, potreste già avere il caching di WordPress incorporato. Ad esempio, le società di hosting WordPress gestite come WP Engine gestiscono le proprie soluzioni di caching.
Gli host WordPress più diffusi, come Bluehost e SiteGround, hanno anche una cache integrata per i loro utenti.
Se si utilizza un web application firewall come Sucuri o Cloudflare per migliorare la sicurezza di WordPress, è disponibile anche una cache per velocizzare il sito e ridurre i tempi di inattività.
Infine, la maggior parte dei browser Web moderni memorizza anche le versioni in cache delle pagine sul browser Web.
Perché cancellare la cache del sito WordPress?
A volte la cache non si accorge che sono state apportate delle modifiche al vostro sito WordPress. Invece di caricare la nuova versione del sito, l’utente rimarrà bloccato a vedere la vecchia versione.
In questo modo si eviterà che sia l’utente che i visitatori vedano gli aggiornamenti effettuati.
La cancellazione della cache di WordPress assicura che la versione più recente del vostro sito web sia sempre disponibile.
Detto questo, vediamo come cancellare la cache in WordPress. Utilizzate i link rapidi qui sotto per passare direttamente al metodo che desiderate utilizzare:

Se preferite le istruzioni scritte, continuate a leggere.
Metodo 1: Cancellare la cache del browser web
Innanzitutto, è necessario cancellare la cache del browser web. La maggior parte dei browser memorizza i contenuti statici del sito web, come fogli di stile, JavaScript, immagini e altri file del sito, per migliorare i tempi di caricamento.
A volte, però, i browser web possono non accorgersi che una pagina web è cambiata. Invece di recuperarne una nuova copia, caricano la pagina dalla versione memorizzata nella cache del browser.
Per cancellare la cache del browser in Google Chrome, fare clic sull’icona del menu, quindi selezionare Altri strumenti ” Cancella dati di navigazione”.
Viene visualizzata una finestra a comparsa in cui è possibile selezionare il contenuto che si desidera rimuovere dalla cache.
Assicurarsi che la casella “Immagini e file nella cache” sia selezionata, quindi fare clic sul pulsante “Cancella dati di navigazione”.
Ora avete cancellato con successo la cache del browser. Potete visitare il vostro blog WordPress per vedere se sta caricando la nuova versione del vostro sito.
Per maggiori dettagli, consultate la nostra guida su come cancellare la cache del browser in tutti i principali browser.
Se ancora non vedete le modifiche apportate al vostro sito web, passate agli altri metodi di questo articolo.

Perhaps I would also add for people using CDNs like CloudFlare, that caching is also enabled there, and additional ‘hidden’ caches might exist on the CDN side. Either a plugin connected to the CDN can clear it, or it needs to be done manually. For instance, in CloudFlare’s dashboard, cache can be cleared in the designated section.
WPBeginner Support says
That is a very good point to remember for those using CDNs

I keep getting a notice from the MonsterInsights plugin in my Site Health that says:
We noticed you’re using a caching plugin or caching from your hosting provider. Be sure to clear the cache to ensure the tracking appears on all pages and posts.
I wasn’t using a caching plugin as far as I knew
WPBeginner Support says
You may want to reach out to your hosting provider to ensure there isn’t something on their end for caching that could be part of the issue.
Admin
Sara says
My host support is telling me the following when I asked them to help me clear my sites cache:
“There is no server-side caching on any of our servers, so this message may be caused by one of your installed WordPress plugins that enables some kind of caching.”
My question is therefore how I can locate what plugin that needs clearing. Do you know?
WPBeginner Support says
You would want to go under Plugins > Installed Plugins and see if any of your plugins say in their description that they are a caching plugin.
Admin
Gopal says
Hi thanks for the article. I have followed every step mentioned but when i designing home page there in no background overly set by me but when browse that page it showing background image but not when i editing page
WPBeginner Support says
You would want to check with the support for your specific theme if clearing the cache is not updating your changes to ensure it is not an issue with the theme itself.

Hi,
I have a question please. Do I need to always clear all the cache manually using w3 total cache or any other plugin.. Isn’t it possible to make it automatically clear all cache daily.
WPBeginner Support says
The caches should clear over time based on the caching you are using, this guide is how to force it to clear in case there are any issues or something that needs to be displayed that isn’t showing.

I have bluehost in-built cache and now I purge all cache from WordPress and how to upload new cache memory again? also, do I need another paid cache service like wp rocket? What would be better
WPBeginner Support says
If you need another cache would be a question of personal preference. Your site will generate a new cache so you don’t need to worry about uploading a new cache.

Can I clear cache from my hosting Cpanel?

It would depend on what caching you’re talking about, if it is caching from your host then you would need to reach out to your hosting provider and they should be able to show you what options are available.

So if you have caching available (and are using) on WPEngine or Securi firewall, then is your article saying that we should NOT implement a caching plugin on wordpress?
WPBeginner Support says
No, you can still use caching on your site with those plugins, this article is to show how you clear the cache if you are having an issue that would require you to clear your cache.

Hello to all,
Great article. I have a closely related question.
When I edit a page of my website in WP, it strangely shows the code of the cdn’s pull zones, not the original code. How do I get back to the original code?
Thanks for the help, Mark
WPBeginner Support says
For that, you would want to check with your CDN to ensure it is properly configured as a likely cause of the problem

Unless you were editing the design and you are clearing your cache to see that update, your design should not be modified.

Hi everyone, it really is a good article….but a question came to my mind. If we face caching problems while building our websites, then how about for visitors to our sites. This may be an insane question, but i am afraid that some of our visitors may not see our updates. Thanks a lot and looking forward an answer from some.
WPBeginner Support says
Following the site and server steps should help allow your users to see your changes.

Am always afraid that Cashing can delete a database or anything within my host file.
But i need to do it to see some changes.

Hi Christian,
No cache files are temporary files which means they can be deleted without affecting your website’s functionality.

Great Article! I have a question. After updating plugins do I have to clear out all my caches again? Thanks!
WPBeginner Support says
Hi Ann,
It is not necessary as most caching plugins are setup to automatically purge cache at regular intervals. However, you can also go ahead and manually clear cache if you find something missing.
Admin
Nick says
Thank you for the helpful post! Clearing my browser cache fixed issues for me, but Is it correct to say that any repeat visitors to my site could run into issues from not clearing their own browser cache? I would like to universally clear cache so that it’s dummy proof and doesn’t require my users to go in and fix it themselves. Is that possible in any way?
Yusuf Bitrus says
Thanks for this awesome suggestions and listings, I think super cache one the best cache plugin I have ever used.
And it is working like a .
I love it
Neal Umphred says
Thanks for your useful article! What does the CLEAR CACHE button on the Publish menu in the WordPress admin section do?
Alex says
It amazes me that most important question has been ignored. How to clear cache saved in other peoples’ browsers? I.E. people who visit you wordpress website and maybe have no idea how to clear icache or that they need to do it. Thousands of plugins but not one which would add some version parameter to all website urls therefore forcing browsers to request them as new files.
Sachin Singhi says
I have also been looking for a way to do the same. Have realised that if we do not enable the cache at all it will work but impact the performance of the website.
Rohan says
Hi, how do I clear cache if I don’t have a cache plugin – taken over a community group site and presumably previous webmaster used then deleted a cache plugin without clearing the cache first?!
Esther Roche says
Hi!
I use Fastest Cache and I was wondering what is the difference between
CLEAR CACHE OF THIS PAGE
DELETE CACHE
DELETE CACHE AND MINIFIED CCS/JS
Can you tell me please?
Thanks in advance and thanks for this post!
Esther
WPBeginner Support says
Hi Esther,
Clear cache of this page, removes the cached files for the page you are currently viewing. Delete cache, deletes cached files and the last deletes everything including minified CSS/JS.
Admin
Esther Roche says
So,
when I make changes in a specific page and someone else can’t see them, I should just use “clear the cache” of that page; but if I make changes to a couple of pages or more, I should either clear cache of each separately or use “delete cache”, which would let them see the changes in the whole site. Is this right?
Thanks again for your patience!
WPBeginner Support says
Hi Esther,
Most caching plugins will automatically clear the cache for a page when you make changes those pages. You will only need to use those features if you are working on your website’s theme or adding some new plugin and those changes are not showing up on your website.
Cherisa says
When I try to install WP Super Cache, I get the message that says “Plugin not allowed on our system due to performance, security, or compatibility concerns. Contact support with any questions”. But at the bottom there’s a check to tell me that it is “compatible with your version of wordpress”. This is the same with W3 Total Cache. What is wrong?
WPBeginner Support says
Hi Cherisa,
Some WordPress hosting companies block caching plugins because they have their own caching installed on their servers. Please contact your hosting provider to confirm.
Admin
Andy says
Similar problem here. Nothing happens when you click on my menu on mobile devices.

Not using a plugin but my CSS changes are not showing in Chrome until the cache is cleared. How do I ensure that my website visitors get the new styling without asking them to clear their browser’s cache.
NB: Its only on Chrome.
Thanks.

Looking for the same answer, Whenever making change in CSS it’s not showing till hard refresh and it’s not suggestible to ask visitor to do hard refresh. So, How we can serve new css changes to the visitors? How to clear all the cookies/browser cache file.
As of now I am using W3 Total Cache plugin, Even after clicking on Performance > Dashboard > Empty All Caches it’s not showing new changes until hard refresh. Can you please suggest some good method for wordpress? I am not using any version css version number as well as GT Matrix suggesting to remove query string I have removed using function.php
Waiting for some positive feedback.

Thanks but how frequently which should clear caches . Also would be better if you can mention sequence of caches to be clear. So we can take note of it point by point
Jeremy says
Good read. Didn’t know about the Sucuri caching. Also, recommending adding a tip for the browser cache. CTRL + SHIFT + R usually works just as well by forcing a refresh that bypasses cache and keeps you having to dump your browser cache, every time.
Dan Kapellen says
This is a valuable article. I learned much about the role of cache, how to optimize its use and maintenance measures. Thank you.
