Why Can’t I Add or Install Plugins in WordPress? (4 Easy Fixes)

One of the most common questions our readers ask us is: “Why can’t I add plugins in WordPress?”.

This question usually has a follow-up where the user is seeing an upgrade message or their admin area doesn’t have the Plugins menu. If you are dealing with this issue, then you are in the right place.

In this article, we will explain why you cannot add or install plugins in WordPress.

Why Can't I Add or Install Plugins in WordPress

2. You Are Facing the Memory Limit Issue

The second most common scenario is that you can see and access the Plugins page, but you can’t install plugins. When you try to install plugins, you will see an error message.

This error is usually caused by the PHP memory limit. WordPress is written using the PHP scripting language, and each PHP script uses a certain amount of memory.

There are settings in your WordPress hosting and inside the WordPress core that define the amount of memory a PHP script can use.

When a process reaches this limit, it either gets terminated or shows an error like this on your WordPress website:

Fatal error: Allowed memory size of 67108864 bytes exhausted

The quick fix to this problem is increasing your PHP memory limit. You can do that by adding this line to your wp-config.php file:

define('WP_MEMORY_LIMIT', '256M');

For more detailed instructions, see our guide on how to fix the WordPress memory exhausted error.

3. There Are User Role Restrictions

WordPress comes with a built-in user role management system. Sometimes web developers don’t give Administrator access to their clients. Instead, they create an Editor account for them.

Only Administrators can install and activate plugins on a WordPress site. If you are the owner of the website, then you need to ask your developer to make sure that you have Administrator permissions.

4. You Are on a Multisite Network

Another possible reason that you can’t see the Plugins menu in WordPress is if your site is part of a WordPress multisite network, and the network admin has disabled the Plugins menu item on the network’s sites.

  1. I can see plugin widget in my dashboard but when I clink on add plugin, there are no plugins. I just see an error:
    “An unexpected error occurred. Something may be wrong with or this server’s configuration. If you continue to have problems, please try the support forums.”
    If I search a plugin name in search bar, the page refreshes but finally this massage appears again.
    what did happened?

    • For that error, we would recommend checking with your hosting provider to see if they have the specific error logged or if they may have a setting in their system that may have blocked the connection to


  2. How ridiculous. I have several websites and I was going to create a new WordPress-based site that needed to use a comparison chart but I’m not willing to pay $300 a year for plugins. I’ll go elsewhere I guess.

    • As we say in that section, if you do not want to pay $300 per year, we would recommend using which is a WordPress site on another hosting provider :)

    • If the plugin is one you’re downloading from an external site you would want to reach out to the plugin’s support with that error message. If it is a custom plugin then you would want to ensure your plugin name is set as a comment in the header.


  4. Hi, I tried to add new plugin, and theme. But I am currently getting 403 Forbidden error. What can I do?

  5. I have a multisite and I installed several plugins but one isn’t showing. I can see it when I go to plugins and I have activated it but it is not showing up in my dashboard so I cant use it. Help. Why isn’t a particular installed and activated plugin showing up in m dashboard but other plugins are?

    • Not all plugins work with multisite installations, we would recommend checking with the support for that plugin and they would be able to help with any issues like this.


  6. Hi,
    Thank you for sharing knowledge. We have a wordpress website hosted on our company internal server. Now we would like to migrate it to our cloud platform.
    I tried to click Add new plugin to install “All-in-One WP Migration”. However whenever I click on ‘Add new’ link server is returning 503 error. Rest all links on admin page works fine.
    Any suggestions?
