L’une des questions les plus fréquentes que nous posent nos lecteurs est la suivante : » Pourquoi ne puis-je pas ajouter des extensions dans WordPress ? « .
Cette situation se produit généralement lorsque l’utilisateur/utilisatrice voit un message de mise à niveau ou que sa zone d’administration ne dispose pas du menu « Plugins ». Si vous êtes confronté à ce problème, vous êtes au bon endroit.
Dans cet article, nous allons expliquer pourquoi il n’est pas possible d’ajouter ou d’installer des extensions dans WordPress.
Ce guide a listé 5 des principales raisons pour lesquelles vous ne pouvez pas ajouter ou installer des extensions dans WordPress. N’hésitez pas à utiliser les liens rapides ci-dessous pour aller à/au Sujet spécifique qui s’applique à votre situation :
1. Vous êtes sur WordPress.com
WordPress.com est un service d’hébergeur de blogs qui propose une version limitée du célèbre logiciel auto-hébergé WordPress. Consultez notre guide sur la différence entre WordPress.com et WordPress.org pour plus de détails.
Les utilisateurs de WordPress.com ne peuvent pas installer d’extensions à moins de passer à l’offre Business ou à une offre supérieure, à partir d’environ 300 $ par an. Si vous bénéficiez d’une offre gratuite, personnelle ou premium, vous ne pouvez pas installer d’extensions tierces.
Si vous ne souhaitez pas payer ce montant, vous pouvez déplacer votre blog de WordPress.com à WordPress.org.
Si vous avez besoin d’aide, vous pouvez utiliser notre service gratuit de configuration de blog WordPress. Indiquez simplement que vous souhaitez que nous transférions votre site, et nous le ferons gratuitement.
2. Il existe des restrictions concernant le rôle des utilisateurs/utilisatrices.
WordPress est doté d’un système de gestion des rôles des utilisateurs/utilisatrices intégré. Parfois, les développeurs/développeuses ne donnent pas l’accès Administrateur/administratrice à leurs clients. Au lieu de cela, ils leur créent un compte d’éditeurs/éditrices.
Seuls les administrateurs/administratrices peuvent installer et activer des extensions sur un site WordPress. Si vous êtes le propriétaire du site, vous devez demander à votre développeur/développeuse de s’assurer que vous disposez des droits d’administrateur/administratrice.
3. Vous êtes confronté à un problème de limite de mémoire
Le deuxième scénario le plus courant est que vous pouvez voir et accéder à la page des extensions, mais que vous ne pouvez pas installer d’extensions. Lorsque vous essayez d’installer des extensions, un message d’erreur s’affiche.
Cette erreur est généralement causée par la limite de mémoire de PHP. WordPress utilise le langage de script PHP et chaque script PHP utilise une certaine quantité de mémoire.
Il existe des réglages dans votre hébergeur WordPress et dans le cœur de WordPress qui définissent la quantité de mémoire qu’un script PHP peut utiliser.
Lorsqu’un processus atteint cette limite, il se termine ou affiche une erreur comme celle-ci sur votre site WordPress:
Erreur fatale : La taille de mémoire autorisée de 67108864 octets est épuisée.
La solution rapide à ce problème est d’augmenter la limite de mémoire de PHP. Vous pouvez le faire en ajoutant cette ligne à votre fichier wp-config.php:
define('WP_MEMORY_LIMIT', '256M');
Pour des instructions plus détaillées, consultez notre guide sur la façon de corriger l’erreur WordPress memory exhausted.
4. Vous êtes sur un réseau multisite
Une autre raison possible pour laquelle vous ne pouvez pas voir le menu Plugins dans WordPress est que votre site fait partie d’un réseau multisite WordPress et que l’admin du réseau a désactivé l’élément de menu Plugins sur les sites du réseau.
C’est à peu près le même scénario que pour WordPress.com. Les admin du réseau doivent tenir compte de la stabilité du serveur, de la sécurité de WordPress et des problèmes d’équilibrage de la charge. Pour résoudre ce problème, vous pouvez demander à votre administrateur/administratrice réseau d’installer des extensions pour vous.
Pour en savoir plus sur ce Sujet, consultez notre guide sur les raisons pour lesquelles vous ne voyez pas toutes les extensions sur les installations multisites de WordPress.
5. Vous avez téléversé le mauvais fichier d’extension.
Imaginons que vous souhaitiez téléverser le fichier d’une extension tierce, mais que WordPress affiche un message d’erreur comme ci-dessous :
Dans ce cas, vous pouvez vérifier si vous téléversez le bon fichier. Les fichiers d’extension sont généralement livrés dans un paquet .zip, ce qui signifie qu’ils utilisent le format .zip.
Vous pouvez également vérifier si les fichiers de contenu zip que vous avez téléchargés sont compatibles. Toutes les extensions tierces ne proviennent pas de sources fiables, et c’est peut-être la raison pour laquelle elles ne téléversent pas correctement.
En savoir plus sur l’installation des extensions, consultez nos guides ci-dessous :

- Guide du débutant : Comment choisir la meilleure extension WordPress
- Faut-il installer des extensions qui n’ont pas été testées avec votre version de WordPress ?

Evan Cleary says
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 says
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 says
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:

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 says
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 says
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

Hi.Why is it my comment section is closed?Even if i downloaded comment plugin it seems nothing changed
WPBeginner Support says
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.
