Dopo aver installato WordPress, la prima cosa che ogni principiante deve imparare è come installare un plugin per WordPress. La padronanza di questa abilità è fondamentale per sbloccare il pieno potenziale del vostro sito web.
In parole povere, i plugin di WordPress sono come applicazioni per il vostro sito web. Consentono di aggiungere nuove caratteristiche, come un modulo di contatto, una presentazione, un carrello e altro ancora.
Con migliaia di plugin gratuiti e a pagamento disponibili, le opportunità di potenziare il vostro sito web sono praticamente infinite. In questa guida vi mostreremo passo dopo passo come installare un plugin per WordPress.
Prima di iniziare
Se si utilizza WordPress.com, non è possibile installare plugin a meno che non si effettui l’aggiornamento al piano business.
Spesso riceviamo lamentele da utenti che dicono di non riuscire a vedere il menu dei plugin nella loro Bacheca di WordPress. Questo accade perché utilizzano WordPress.com, che ha delle limitazioni.
D’altra parte, è possibile installare qualsiasi plugin sul proprio sito web WordPress.org ospitato in esterno direttamente dalla scatola.
Se avete ancora qualche dubbio, potete consultare il nostro articolo che parla di WordPress.org ospitato all’esterno e WordPress.com.
Se volete passare da WordPress.com a WordPress.org, leggete il nostro tutorial su come passare correttamente da WordPress.com a WordPress.org.
Come installare un plugin di WordPress
Per semplificare le cose, abbiamo creato un video tutorial su come installare un plugin di WordPress, che potete vedere qui sotto.
Se volete seguire istruzioni scritte, continuate a leggere. Ecco una rapida panoramica di tutti i metodi che metteremo in copertina per installare un plugin di WordPress sul vostro sito web:

Installare un plugin usando la ricerca dei plugin di WordPress
Il modo più semplice per installare un plugin di WordPress è utilizzare la ricerca dei plugin. L’unico inconveniente di questa opzione è che il plugin deve essere presente nella directory dei plugin di WordPress, che è limitata ai plugin gratuiti.
La prima cosa da fare è visitare la pagina Plugin ” Aggiungi nuovo all’interno dell’area di amministrazione di WordPress.
Verrà quindi visualizzata una schermata come quella riportata nello screenshot qui sopra.
Ora è possibile trovare il plugin che si desidera installare digitando il nome del plugin o la funzionalità di cui si ha bisogno. Ad esempio, qui digitiamo‘WPForms‘ nella barra di ricerca.
Al termine del caricamento, si vedrà un gruppo di elenchi come nell’esempio seguente:
Potete scegliere il plugin più adatto a voi. Poiché stavamo cercando WPForms, il miglior plugin per moduli di contatto per WordPress, faremo clic sul pulsante “Installa ora” accanto ad esso.
WordPress scaricherà e installerà il plugin per voi. Una volta terminata l’installazione, noterete che il pulsante “Installa ora” cambia in “Attiva”.
Si noti che un plugin di WordPress non funziona finché non lo si attiva. Quindi, fate clic sul pulsante “Attiva” per iniziare a utilizzare il plugin sul vostro sito WordPress.
Tutto-in-uno! Avete installato con successo il vostro primo plugin per WordPress.
Il passo successivo consiste nel configurare le impostazioni del plugin. Poiché queste impostazioni variano per ogni plugin, non saranno oggetto della presente copertina.
Installare un plugin utilizzando l’uploader dei plugin dell’amministrazione di WordPress
I plugin WordPress a pagamento non sono elencati nella directory dei plugin di WordPress e non possono essere installati con il primo metodo.
Per questo motivo, WordPress dispone del metodo uploader per l’installazione di tali plugin. In questa sezione vi mostreremo come installare i plugin di WordPress utilizzando l’opzione uploader nell’area di amministrazione.
Per prima cosa, è necessario scaricare il plugin dalla fonte, che sarà un file zip. Una volta fatto, potete navigare su Plugin ” Aggiungi nuovo dall’area di amministrazione di WordPress.
Dopodiché, basta cliccare sul pulsante “Uploader Plugin” in alto nella pagina.
Si aprirà il modulo di uploader del plugin.
Qui si dovrà fare clic sul pulsante “Scegli file” e selezionare il file del plugin scaricato in precedenza sul computer.
Dopo aver selezionato il file, fate clic sul pulsante “Installa ora”.
WordPress caricherà il file del plugin dal computer e lo installerà per voi. Al termine dell’installazione, verrà visualizzato un messaggio di successo come questo.
A questo punto, non resta che fare clic sul pulsante “Attiva plugin” per iniziare a usare il plugin.
Il passo successivo consiste nel configurare le impostazioni del plugin in base alle proprie esigenze. Anche in questo caso, poiché queste impostazioni variano per ogni plugin, non ne parleremo in questa pubblicazione.
Installare manualmente un plugin di WordPress utilizzando l’FTP
In alcuni rari casi, il vostro fornitore di hosting WordPress potrebbe avere restrizioni sui file che limitano la possibilità di installare un plugin dall’area di amministrazione.
In questa situazione, la cosa migliore è installare il plugin manualmente tramite FTP. Tuttavia, il metodo del gestore FTP è il meno facile per i principianti.
Prima di iniziare, è necessario scaricare il file zip del plugin ed estrarlo sul computer.
L’estrazione del file zip del plugin crea una nuova cartella con lo stesso nome. È necessario installare manualmente il plugin di WordPress in questa cartella con un client FTP.
Ora, assicuratevi di avere accesso al vostro host attraverso il gestore FTP. Se non avete il nome utente e la password dell’FTP, contattate il vostro fornitore di hosting WordPress e chiedeteglieli.
Una volta preparata la cartella zip estratta e i dati di accesso FTP, è possibile aprire il client FTP sul computer.
La prima cosa da fare è collegarsi al proprio sito web utilizzando le credenziali di accesso FTP fornite dal proprio host. Una volta connessi, ci si può dirigere verso la cartella /wp-content/plugins/ del sito web.
È sufficiente caricare la cartella estratta dal file zip nella cartella /wp-content/plugins/ sul proprio server.
Dopo aver caricato i file, è necessario visitare l’area di amministrazione di WordPress e fare clic sulla voce di menu “Plugin”.
Si dovrebbe vedere che il plugin è stato installato con successo sulla pagina dei plugin. Per iniziare a utilizzare il plugin, fare clic sul link “Attiva” nella sua sezione.
Dopo l’attivazione, potrebbe essere necessario configurare le impostazioni del plugin. I plugin di WordPress hanno impostazioni proprie, che differiscono da un plugin all’altro, quindi non le descriveremo qui.
FAQ sull’installazione dei plugin di WordPress
Come principianti, potreste avere alcune domande sull’installazione dei plugin di WordPress. Essendo il più grande sito di risorse per WordPress, ne abbiamo sentite molte.
In questa sezione risponderemo ad alcune delle domande frequenti sull’installazione dei plugin di WordPress.
1. Come posso trovare i migliori plugin di WordPress da installare sul mio sito web?
Solo nella directory dei plugin gratuiti di WordPress ci sono più di 59.000 plugin per WordPress e molti altri sono disponibili come plugin premium. Questo rende un po’ difficile trovare il plugin migliore per la caratteristica di cui si ha bisogno.
Abbiamo compilato un elenco di tutti i plugin WordPress essenziali di cui ha bisogno la maggior parte dei siti web WordPress. Abbiamo anche un tutorial dettagliato su come scegliere il miglior plugin per WordPress che vi mostra cosa cercare quando cercate i plugin.
2. Qual è la differenza tra plugin attivati e installati?
WordPress consente di installare un plugin e di non utilizzarlo affatto. Per utilizzare un plugin sul proprio sito, è necessario attivarlo.
È possibile vedere i plugin attivati visitando la pagina “Plugin” nell’area di amministrazione di WordPress. Saranno in evidenza con uno sfondo blu.
I plugin con sfondo bianco sono stati attivati sul sito web, ma non sono attivi.
3. Devo eliminare i plugin inattivi?
Se non utilizzate un plugin, vi consigliamo di eliminarlo dal vostro sito web. Per saperne di più su questo argomento, potete leggere il nostro articolo sul perché eliminare i plugin inattivi in WordPress.
4. Quanti plugin posso installare in WordPress?
Potete installare tutti i plugin di WordPress di cui avete bisogno. Non è il numero di plugin a influire sulla velocità del sito web, ma la loro qualità. Per ulteriori informazioni, consultate gratuitamente il nostro articolo su quanti plugin WordPress dovreste installare.
5. Come si disinstalla un plugin di WordPress?
È possibile disinstallare un plugin di WordPress visitando la pagina “Plugin” nell’area di amministrazione di WordPress.
Se il plugin che si desidera rimuovere è attualmente attivato, è necessario innanzitutto disattivarlo. Dopodiché, è sufficiente fare clic sul pulsante “Elimina” per rimuoverlo dal sito web.
Per istruzioni più dettagliate, potete consultare la nostra guida su come disinstallare correttamente un plugin di WordPress.
Speriamo che questo vi abbia aiutato a imparare come installare i plugin di WordPress. Successivamente, potreste voler consultare la nostra categoria dei plugin, dove scriviamo dei migliori plugin di WordPress per realizzare qualsiasi cosa vogliate fare. Ciascuno di questi articoli è corredato da istruzioni passo-passo su come impostare i singoli plugin.

WordPress plugins are a great thing, but I would totally disagree with the statement in the FAQ article that you can install as many plugins as you need. You are minimally limited by the memory limit, which is set on the hosting and which will eventually run out. I think that a reasonable solution is up to 20 plugins. Then the amount will start to show on the speed of the website. A combination of plugin and snippet is good. If not everything can be solved immediately with a plugin, and there is a snippet for many problems.
WPBeginner Support says
It heavily depends on the plugin for how much they would affect a site, we would recommend taking a look at our article below:

Moinuddin Waheed says
Most often I use the first method by going through the plugin options and searching in the WordPress repository.
it does make a lot of sense in terms of knowing that the repository is always safe to use.
I have used upload methods as well mostly for premium plugins as they come directly from plugins own websites.
Much appreciated the efforts of wpbeginner to make even the simple things more simple.

It sounds like you are either installing a massive plugin or there may be an issue with your hosting, we would recommend reaching out to your hosting provider to ensure there is no error from their end.

Please contact your WordPress hosting provider. It is likely that the user account you are using doesn’t have administrator privileges.

Hi. I’m uploading a plugin like in the second example…. but which file do I upload? The maps one I have purchased is a folder with all the files inside i.e. documentation – I don’t know which bit to upload! Please help
WPBeginner Support says
Hi Rose,
When you purchase a WordPress theme you get it in a zip file. You don’t need to unzip that file and upload it.
You try again by downloading the plugin again.
Alternately, you can upload the plugin folder to your WordPress website manually using FTP. You will need to upload the folder to /wp-content/plugins/ folder.
Admin
Digember says
Thanks for the guide, very helpful.
Upload via WordPress directory gives error to me, so I used the FTP method to upload a downloaded plugin and it worked.

I am trying to upload a plugin onto my site. I have followed it up to the point where you click “Upload Plugin” on the Add New section of the plugin page. However, whenever I click the button nothing happens at all.
Niels Tang Graverholt says
Thanks for a great page
BUT: When I have installed and activated, what do I do then to use the plugin??
WPBeginner Support says
Hi Niels,
It actually depends on the plugin you are using. Some plugins add a new page where you can configure plugin settings. This page is typically located under Settings menu in your WordPress admin bar. Other plugins may place it under other menu items in admin area. Check the plugin’s details page for instructions.

Hello,
I would love some assistance with a plugin please. I have uploadd a new theme to my site with all of the required plugins, all of which have successfuly installed, but one (Revolution Slider).
I am getting the following message:
Unpacking the package…
Installing the plugin…
Destination folder already exists…./public_html/wp-content/plugins/revslider/
Plugin install failed.
I have gone into my file manager and can see that there is already a folder with the required plugin installed, however when I try to access the plugin from the WP dashboard, it still says it’s not been installed (and I can’t find it in inactive either).
If anyone has any advice, I’d be super grateful! Thanks!
WPBeginner Support says
Hi Martyna,
You’ll need to delete the plugin folder from your website using the File Manager. After that you’ll be able to upload and install the plugin again.

Hi
How do I install a plugin in localhost?
I’ve tried adding it manually in : xampp/htdocs/mywebsite/wp-content/plugins
but when I got back to the site plugins area its still not there. I’ve cleared cache just in case there was a bit of a lag but still nothing.
I used this process to add a new theme and it worked fine.
Is there something else I should be doing?
Thanks
WPBeginner Support says
Hey Deborah,
May be the plugin you are trying to add has incorrect plugin header which could stop WordPress from showing it as a plugin. Try adding some other plugin, to make sure this isn’t the case.

Brock says
Hello, thanks for the great info. I’ve purchased Yoast premium, downloaded it, but then when i try to upload to my site, its has broken the download into a bunch of individual folders. I’m certain i probably need all of them, but it will only let me choose one?
So how should i proceed?
WPBeginner Support says
Hi Brock,
Premium plugins come as a zip file. After downloading it to your computer, you don’t need to unzip or open that file. If you do that, then you will see individual folders packed inside the plugin.
If for some reason you cannot locate the plugin’s zip file, then you can try uploading it using FTP.

Fatal error: Can’t use function return value in write context in /home2/gnastac/public_html/topbusinessgrowth.com/wp-content/plugins/insert-headers-and-footers/ihaf.php on line 102
Could you help me to fix it?
WPBeginner Support says
Hi Gelu Nastac,
First you will need to deactivate the plugin. If you are unable to access the WordPress admin area, then see our guide on how to deactivate plugins when not able to access admin area.
After that you will need to install the updated version of the plugin. Let us know if this worked.

I would like to ask for help on plugins. I’m new to this area and I’m currently taking an online course. However, I haven’t gotten an answer from them yet.
I’m trying to activate/add my first plugin. I understand a plugin can be 1 file. In my case it’s a php file and its contents is just comments at this point.
When I go to plugins in my admin site I dont see the file. so I’ve tried using the ‘add new’ link and I proceed to upload the file both as a singe file and as a zip file and here are the errors I get:
Unpacking the package…
Installing the plugin…
The package could not be installed. No valid plugins were found.
Plugin install failed.
OR i get this error:
Unpacking the package…
The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature

Thank you.
WPBeginner Support says
If you cannot see the plugins menu, then most probably your site is still redirecting you to the WordPress.com dashboard. It is also possible that your site is still hosted with WordPress.com and you just added a domain name to your existing WordPress.com blog.
