Una delle domande più frequenti che i nostri lettori ci pongono è: “Perché non posso aggiungere plugin in WordPress?”.
Questa situazione si verifica di solito quando l’utente vede un messaggio di aggiornamento o l’area di amministrazione non ha il menu dei plugin. Se state affrontando questo problema, siete nel posto giusto.
In questo articolo spiegheremo perché non è possibile aggiungere o installare plugin in WordPress.
In questa guida sono elencati 5 dei principali motivi per cui non è possibile aggiungere o installare plugin in WordPress. Sentitevi liberi di usare i collegamenti rapidi qui sotto per passare all’argomento specifico che si applica alla vostra situazione:
1. Siete su WordPress.com
WordPress.com è un servizio di hosting per blog che offre una versione limitata del popolare software WordPress self-hosted. Per maggiori dettagli, consultate la nostra guida sulla differenza tra WordPress.com e WordPress.org.
Gli utenti di WordPress.com non possono installare plugin a meno che non effettuino l’aggiornamento al piano Creator o superiore, che parte da chi è a 25 dollari al mese. Se siete su un piano Gratuito, Principiante o Explorer, non potete installare plugin di terze parti.
Se non volete pagare questa cifra, potete spostare il vostro blog da WordPress.com a WordPress.org.
Se avete bisogno di aiuto per farlo, potete utilizzare il nostro servizio gratuito di configurazione del blog WordPress. Basta indicare che volete che trasferiamo il vostro sito e lo faremo gratuitamente.
Suggerimento professionale: Volete creare un sito web su WordPress.org senza problemi? I nostri servizi WPBeginner Pro possono aiutarvi a dare il via alla vostra presenza online e a costruire un bel sito senza alcuno sforzo.
2. Esistono limitazioni di ruolo per gli utenti
WordPress ha un sistema integrato di gestione dei ruoli degli utenti che assegna diversi livelli di accesso agli utenti del sito web.
Gliamministratori sono il ruolo più alto dell’utente e hanno pieno accesso a tutte le funzionalità del sito WordPress, compresa l’aggiunta, l’installazione e l’attivazione di plugin.
D’altra parte, gli Editori, gli Autori, i Collaboratori e gli Abbonati non possono installare plugin.
Se state elaborando in corso un sito web ma non vedete il menu “Plugin”, è possibile che non abbiate l’accesso come amministratore.
In questo caso, se vi fidate della persona che gestisce il sito web (ad esempio, uno sviluppatore o un webmaster), potete chiedere gentilmente di concedervi le autorizzazioni di amministratore per installare i plugin di cui avete bisogno.
3. Problema di limite di memoria
Il secondo scenario più comune è quello in cui è possibile vedere e accedere alla pagina dei plugin, ma non è possibile installarli. Quando si tenta di installare i plugin, viene visualizzato un messaggio di errore.
Questo errore è solitamente causato dal limite di memoria di PHP. WordPress è scritto utilizzando il linguaggio di scripting PHP e ogni script PHP utilizza una certa quantità di memoria.
Ci sono impostazioni nel vostro hosting WordPress e nel nucleo di WordPress che definiscono la quantità di memoria che uno script PHP può utilizzare.
Quando un processo raggiunge questo limite, viene terminato o mostra un errore come questo sul vostro sito WordPress:
Errore irreversibile: La dimensione di memoria consentita di 67108864 byte è esaurita.
La soluzione rapida a questo problema è aumentare il limite di memoria di PHP. È possibile farlo aggiungendo questa riga al file wp-config.php:
define('WP_MEMORY_LIMIT', '256M');
Per istruzioni più dettagliate, consultate la nostra guida su come risolvere l’errore di esaurimento della memoria di WordPress.
Si noti che, sebbene l’aumento del limite di memoria di PHP possa talvolta correggere il problema e consentire l’installazione dei plugin, è importante capire che non è sempre la soluzione ideale.
Il codice dannoso potrebbe sfruttare un limite di memoria elevato per consumare più risorse del previsto, con un potenziale impatto sulla sicurezza del sito WordPress.
Prima di modificare il limite di memoria, si consiglia di consultare il proprio fornitore di hosting WordPress. Questi può analizzare le esigenze specifiche del vostro sito web e consigliarvi un aumento sicuro e appropriato del limite di memoria, se necessario.
Per saperne di più, potete leggere il nostro articolo su come richiedere correttamente l’assistenza di WordPress.
4. Siete su una rete multisito
Un’altra possibile ragione per cui non si riesce a vedere il menu dei plugin in WordPress è se il sito fa parte di un network o di una rete di WordPress multisito.
Un network multisito di WordPress consente di gestire più siti web da un’unica installazione di WordPress. Può essere utile in situazioni in cui è necessario gestire un network o una rete di siti web simili.
Tuttavia, una differenza fondamentale tra un network o una rete di multisiti e una tipica installazione di WordPress è che l’amministratore della rete ha un maggiore controllo sui singoli siti.
In alcuni casi, l’amministratore della rete potrebbe disabilitare il menu dei plugin per singoli siti all’interno della rete per mantenere la coerenza o garantire la stabilità di tutti i siti.
Per risolvere questo problema, potete chiedere al vostro amministratore di rete di installare i plugin per voi.
Per saperne di più su questo argomento, consultate la nostra guida sul perché non si vedono tutti i plugin nelle installazioni multisito di WordPress.
5. Avete caricato il file del plugin sbagliato
Supponiamo di voler caricare un file di plugin di terze parti, ma WordPress continua a mostrare un messaggio di errore come quello riportato di seguito:
In questo caso, si potrebbe verificare se si sta caricando il file giusto. I file dei plugin sono solitamente contenuti in un pacchetto .zip, il che significa che utilizzano il formato .zip.
Si consiglia inoltre di controllare se i file di contenuto zip scaricati sono compatibili. Non tutti i plugin di terze parti provengono da fonti affidabili e questo potrebbe essere il motivo per cui non vengono caricati correttamente.
Per ulteriori informazioni sull’installazione dei plugin, consultate le nostre guide qui sotto:
- Come installare un plugin di WordPress (passo dopo passo)
- Guida per principianti: Come scegliere il miglior plugin per WordPress
- Dovreste installare plugin non testati con la vostra versione di WordPress?
Inoltre, per ridurre al minimo i rischi per la sicurezza, consigliamo di installare solo plugin provenienti da fonti affidabili, come la directory dei plugin di WordPress.org. La directory di WordPress.org ha un processo di revisione e tende a offrire plugin di sviluppatori affidabili.
Ecco alcuni suggerimenti aggiuntivi per la scelta di plugin sicuri:
- Cercate plugin con uno sviluppo attivo e buone valutazioni da parte degli utenti.
- Selezionate la data di aggiornamento per assicurarvi che il plugin sia compatibile con la vostra versione di WordPress.
- Leggete la descrizione e le recensioni del plugin per capire le sue caratteristiche e i potenziali problemi di compatibilità.
Speriamo che questo articolo vi abbia aiutato a capire perché non è possibile aggiungere o installare plugin in WordPress. Potreste anche consultare il nostro elenco dei plugin WordPress indispensabili e la nostra guida sugli errori comuni di WordPress e su come risolverli.

I set up a WordPress site in 2014 and was able to get plugins without going into a business plan. And I sent up another site a few years ago and it was also not any problem to add plugins. As far as I know, it was via WordPress.com and not WordPress.org – I downloaded a theme and editors that and used my own URL hosted by a hosting company. I’m quite confused now as no one seems to be saying that this policy of having to pay for a business plan is a new thing. Is it a new thing?
WPBeginner Support
If your site is on a hosting provider and not the WordPress.com website then it is a WordPress.org site. Having to purchase the business plan on WordPress.com for access to plugins is not something new.

I had one site of mine that had the issue of no option for adding or updating plugins. For some reason define(‘DISALLOW_FILE_MODS’,true); was in my wp-config file.
Once I deleted that line, my plugin options were restored. It took me a while to find this solution. I hope this helps people find this solution.

Thanks for the good article! I am bit confused, because I am super administrator and can’t install any new plugins. I can activate and deactivate plugins for sites or the whole network. But I don’t have the page for plugin installtion. Do you have any suggestions in this case? Thanks!
WPBeginner Support
If you’re using a multisite like it sounds like you are, you would need to install the plugin in the network admin area rather than on the individual sites.

Hello! Same problem here. Cannot ADD plugins.
More details of my site:
WordPress 5.2.2 running Bridge theme, so WordPress.org. no .com
Hostgator for hosting
I am an admin and no one else has ever done any work on the site, so I am the only admin for sure.
Please help and thanks in advance!
WPBeginner Support
You may want to check with your hosting provider to ensure there are no errors on their end that could be part of the problem. You could try checking your folder permissions as well similar to the article here: https://www.wpbeginner.com/beginners-guide/how-to-fix-file-and-folder-permissions-error-in-wordpress/

Don’t know what I’m doing wrong with new wordpress.com blog (true newbie). My menu doesn’t look like those above. All I see are the following 7 options, all are listed on the left: Site Identity, Colors & Backgrounds, Fonts, Header Image, Menus, CSS and Widgets. I guess my question is, is this as it should be for the free (.com) site? Is it from this menu that I will create and complete my free blog?
Sorry to be so ignorant about this. I think I’m missing something as I don’t imagine it’s supposed to seem so confusing.
Thank you!
Mazie
WPBeginner Support
Sadly, our tutorials are for WordPress.org rather than WordPress.com which is what you’re using would be part of the confusion. If you go to the wp-admin area of your WordPress.com site the admin area will look similar but you will still have the WordPress.com limitations.

Hello,
Thank you for sharing such a valuable info.
Maybe this’s a bit off topic question.
I’m having a small issue at the moment with adding a new submenu page.
So basically I got an Astra Theme (not a pro version) with Beaver Builder.
I add the page as usual then add to the menu under sub-item, all looks good.
But when I click on the sub menu page it doesn’t take me there. It basically takes me to a home page.
What could be an issue? Could you help me please?
Thank you

WPBeginner Support
Hi Angelo,
If comments are closed on all your articles, then go to Settings » Discussion page inside WordPress admin area and check the box next to ‘Allow people to post comments on new articles’ option. Any new article you now add will have comments enabled by default.
For your older article you will have to edit them and then on the post edit screen click on the Screen Options button at the top right corner of the screen. Check the box next to Discussion option. Now scroll down below the post editing area and you will see a Discussion meta box where you need to check the option ‘Allow Comment’ option.

I was added as ‘admin’ in a multisite WordPress so I couldn’t see the Plugins. Asked for the ‘network admin’ to enable Plugins in ‘Network Configurations’ but looks like that just allows me to see the Plugins, still not able to install new plugins.

Hey Rafael,
The network admin or super admin can allow individual site admins to activate or deactivate plugins on their own.
