Why can't I add or install plugins in WordPress?

Listen to this article

One of the most common questions newbies to WordPress ask is:Why can't I add plugins to WordPress?". It usually depends on what the user sees the update message, or if there is no plugins menu in the user's admin area. If you have this problem, you have come to the right place. In this article, I will explain why you cannot add or install plugins in WordPress.

The content of the article:

• 1. You are on WordPress.com
• 2. You have memory limit issues
• 3. User role restrictions
• 4. You are on a multisite network

1. You are on WordPress.com

WordPress.com is a blog hosting service that offers a limited self-hosted version of the popular WordPress software.

WordPress.com users cannot install plugins unless they upgrade to the business plan, which costs about $299 per year. If you are on a Free, Personal, or Premium plan, you cannot install third-party plugins.

If you don't want to pay $299 a year, you can move your blog from WordPress.com to WordPress.org.

2. You have memory limit issues

The second most common situation is that you can view and access the plugins menu, but you can't install plugins.

Error notifications are usually caused by PHP memory limits. There are settings in WordPress hosting and WordPress core that determine the amount of memory that PHP scripts can use. When a process reaches this limit, it either terminates or throws an error like:

Fatal error: Allowed memory size of 67108864 bytes exhausted

A quick solution to this problem is to increase the PHP memory limit. You can do this by adding the following line to your wp-config.php file:

• define('WP_MEMORY_LIMIT', '256M');

3. User role restrictions

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

Only administrators can install and activate plugins on WordPress sites. If you are the site owner, you need to ask the developer to make sure you have administrator rights.

4. You are on a multisite network

Another possible reason why you are not seeing the plugins menu in WordPress could be that your site is part of a WordPress multisite network and the network administrator has disabled the plugins menu item on the network site.

Almost the same as WordPress.com. Network administrators need to consider server stability, WordPress security, and load balancing issues. To fix this, you can ask your network administrator to install the plugin for you.
