WordPress plugin conflict?

If you don’t know how to deal with it or what to focus on, it can be a total disaster. Imagine installing a new plugin or updating something and everything stays the same. The entire site is down. This article reviews the possible causes and conditions of plugin conflicts and provides practical tips for resolving them. If you have encountered this problem before, please wait.

Why are my WordPress plugins having compatibility issues?


Plugins are WordPress extensions created by various developers. WordPress is a dynamic CMS that is constantly updated.

If developers don’t update their plugins to keep up with WordPress updates, plugins become incompatible and create compatibility issues.

Another reason compatibility issues can occur is due to conflicts between different plugins or themes, where the absence of one plugin or theme causes other plugins or themes to not work. Also, if two plugins try to do the same thing in different ways, they might not do anything.

Other causes of plugin compatibility issues include:

  1. Both plugins run the same version of JS.
  2. The plugin installs event handlers on some HTML elements, such as clicks. Event handlers use the prevent() and stopImmediatePropagation() methods. Therefore, event handlers installed by other plugins on the same element will not work on their own.
  3. Plugins use the same filter, so their changes conflict with each other.
  4. Security system plugins may give false positives, so some features may not work.

In this case, the website as a whole may stop working or somehow perform some functions incorrectly. Forms may not work, loading speed may be slow, individual elements may not display, pages may not load.

You can often find advice on the internet to remove and reinstall plugins, but this often does not work.

Install plugins and themes from the same developer.

For example, our JetPlugins work great with the Kava theme. If you install multiple plugins from the same developer, even those They have the same coding standards and use the same frameworks and libraries. So plugins are mainly complementary to each other to work well has been designed. Their updates are synced regularly and compatibility tested before release I do.

The main indicator of plugin conflicts

This site has stopped working: white screen of death, error 500, error 503, error 502, fatal, parsing/syntax error. At the same time, the management panel may or may not stop the operation, depending on the error.
You can see the error message at the top/bottom of the web page or across the screen. Usually, this is a Parse error.
No bugs are shown, but some features just stop working, or new/updated plugins don’t work. Often forms, menus and other interactive elements stop working first.

Helpful tips and fixes at this stage:

All errors with status code 5xx (500-511) are related to communication with the server, especially HTTP requests. Here is a complete list of web bugs. If you see errors 502, 503, 504 and 505, contact your host. You most likely have peak loads that the server can’t handle, downtime, something else that only the host/server admin can handle.


A parse/syntax error means that one of the files is corrupted, and the error message shows the file and line of code that caused the error. As a rule, such errors are found when adding custom code, not a robust plugin, but it can also mean a bug in the updated plugin code, etc.

the white curtain of death. If you can’t go to any page on the web and/or the admin panel, this is it. Go to wp-content > Plugins and rename the suspect plugin (eg, add the word _backup to it) and use FTP to disable the plugin that might be broken and it will automatically disable it.

But, as a rule, one of the most common causes of the white screen of death is a syntax error in the file functions.php or wp-config.php. Make sure you don’t change anything there. If not, restoring from a backup will surely help you.
