2. Issues of Memory Limit

Secondly, the most common issue is the limitation of memory. You can access plugins or themes but not install them. When you want to install, you will see an error message like:

Fatal error: Allowed memory size of 67108864 bytes exhausted

You can fix this issue as soon as possible, just increasing the PHP memory size. The default memory limit is 64M. If you increase it with 128M, 256M, or more, you will upload plugins or themes.

To increase the memory limit, you have to log in to the cPanel. Then click File Manager > public_html. After that, you have to find out the wp-config.php file and go to the edit option by right click of the mouse.

Next, copy the following code and paste it before this line ‘That’s all, stop editing! Happy blogging.’.

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

As a result, your problem will be solved. And you can upload your essential plugins or themes. You can solve this problem in other ways, which I have discussed in the following section.

3. Exceeding File Size Limits

Is memory limit the only reason to upload a file or plugins? No. If your file size is too large, WordPress will not allow you to upload files. Moreover, you will get an error message if your allowable file size is exceeded.

This error message is like this:

The uploaded file exceeds the upload_max_filesize directive in php.ini.

How to fix it? To fix it, you have to go to File Manager > public_html > wp-admin through cPanel. Also, you can access it using FTP. In wp-admin, you will find the php.ini file. If you do not find the php.ini file, you can create a new one.

Open the php.ini file, where you will find the upload_max_filesize. You can overwrite your existing file using the following code or create a new one.

upload_max_filesize = 128M
post_max_size = 256M
memory_limit = 256M
file_uploads = On
max_execution_time = 180

There is another way to fix this issue. From your cPanel, go to MultiPHP INI Editor, which you find in the Software section. Then select your domain from the Basic Mode tab. Scroll down and edit your upload_max_filesize. It is an easy process for those who don’t like coding.

Exceeding File Size Limits

4. User Role Restrictions

WordPress has six types of user roles, which capabilities are predefined. These predefined user roles are Super Admin (for multi-site only), Administrator, Editor, Author, Contributor, and Subscriber. You can create more user roles for your website using some plugins if you need them.

If you are not an administrator user, you can’t install plugins. Sometimes the web developer does not give the administrator role to their clients. Instead of the administrator role, they create an editor role for clients.

WordPress User Role Restrictions

Therefore, if you want to install plugins or themes on your website, you change the role. Otherwise, contact your developer to change it.

5. Multi-Site Network

There is another possible reason, that is why you can’t install plugins on WordPress. If your website is part of a multi-site network, you can’t see the plugin menu. Your network admin may disable menu items for users.

This is almost the same scene as In this case, only a super admin can install a plugin. However, if the super admin allows a user and puts him in the administrator role, he can also do the same.

To solve this problem, contact the super admin to install your plugins. But you should know that not every WordPress plugin works appropriately on a multi-site network website.
