How To Uninstall A Plugin : The Simple Way

As much as it is important to know how to install a plugin, I will explain below why it is important that you know how to uninstall it. If you are looking for ways to permanently remove your plugins, then read this other article we’ve written. Otherwise, you can start with the simple method below:

  1. Within your WordPress admin dashboard, click on Plugins
  2. Scroll to the plugin you wish to uninstall, hover on it, then click on Deactivate
  3. After your plugin has been deactivated, click on Uninstall

Now, why would you ever need to uninstall a plugin when you’ve installed it for a reason in the first place? Because plugins aren’t without risk.

Common WordPress Plugin Issues And How To Avoid Them

1. Conflicts & Breakdowns

WordPress Plugins Can Conflict With Each Other

It is possible for two or more plugins to be incompatible with each other for various reasons. If this happens on your watch, the affected plugins will either stop working, or your website will behave differently. The easiest way to solve this issue is to uninstall the latest plugin you activated, or revert to an older version of the plugin you updated before your website crash.

2. Site Speed

Plugins Can Slow Your Website Down

How is that?

Imagine an instruction manual. The time it takes to reach its last page or conclusion depends on the amount and complexity of text provided right?

In the same light, a plugin is like a book with multiple lines of text or code. The time it takes for your visitor’s computer to load any plugin depends on its code length and complexity.

More plugins mean more code to be read, which in turn means more time spent on loading your website pages. That said, let me stress a point: Your problem may not always be the number of plugins, but their complexity. To learn more about plugin quality, check this article from WP Engine.

How to Mitigate Plugin Conflicts
  • Reduce your use of plugins to a minimum. Instead of using 3 plugins for 3 functions for example, look for a single plugin that performs all 3 functions. More and more plugins are designed to do more.
  • Update your plugins one by one, not in a bulk. It will help you quickly identify a culprit plugin in case your website breaks down.
  • Before you install a plugin, open a Google search tab and search for “[your plugin’s name] plugin conflict”. In your results, pay attention to the versions of the plugin that are being identified to cause trouble. Follow the recommendations in those articles.
  • Create regular backups of your website, so you can revert to a working version if a plugin conflict occurs.
3. Security

Vulnerable WordPress Plugins Can Expose Your Website To Attacks

A 2016 research by WordFence showed that over 50% of WordPress website attacks originated from plugins.

To mitigate plugin vulnerabilities, follow the following instructions:

Do Not Install Abandoned Plugins

No plugin is free of shortcomings. That is why plugin developers constantly improve their plugin’s security and functionality through time. A plugin that doesn’t get updated by the developers eventually falls behind in terms of security and makes your website vulnerable to attack. Hence, you should not install or keep abandoned WordPress plugins on your website.

Update Your Plugins to Their Recent Versions

Do this provided the recent version was made available for “some time”.

Why? Because developers are human. It is not uncommon for the latest version of plugins to be released with yet unidentified conflicts with other plugins. Let other people install it first, use it, report issues, have them fixed, before you update yours. Since those are not likely to happen within just a day after a plugin’s release, give every plugin version some time before you update. You want it to be recent, but not too recent.

Use Plugins From Trustworthy Sources

Hacked versions of plugins often come with inbuilt, exploitable vulnerabilities. For that reason, it is advisable that you upload plugins from trustworthy sources only, like the original plugin authors or the official WordPress plugin directory.


It is easy to setup a WordPress plugin once you’ve identified the need for one. In 8 clicks or less, you can either install your WordPress plugin through the plugin directory page or by uploading its .zip file through your dashboard.
