Type of Plugin Conflict

As of today, when we are writing this blog, over 60,000 plugins are available in WordPress. They are developed by numerous developers with the intent of serving different interests. So, no way we can assure that each of them will be compatible with others and make no conflict.

Conflicts are obvious if a plugin is incompatible with others based on class, language, framework, etc. There are basically three types of plugin conflicts in WordPress. They are:

  1. Conflicts between two or more plugins.
  2. Conflicts between the installed theme and plugin(s).
  3. Conflicts between the plugin(s) and the present WordPress version.

What are the Symptoms of Plugins Conflicting in WordPress?

Plugins power up a WordPress site and make it functional. But if there is a conflict between the plugins installed in WordPress, your web functionality will get stuck, and you will experience the following symptom(s).

  • Your WordPress site may stop functioning suddenly, and you can’t access the dashboard.
  • Some of your web elements will disappear, like your WordPress block editor may stop functioning.
  • The web speed may go unjustifiably down and get stuck sometimes.
  • You may not be able to update your plugins and operate them smoothly.

If you face any such problem, you have to check first if there is any plugin conflicting with your site. The next section will deal with this topic.

How to Check Plugin Conflict in WordPress

You can check plugin conflict in WordPress in two ways: manually or using a plugin. Both of them are simple and effective. Here, we will explain these methods so you can choose the right one per your preferences. Let’s get started.

Method 01: How to Check Plugin Conflict in WordPress & Fix Theme

There are several steps involved in the manual method of checking plugin conflict. It may take a bit more time, but it will help you identify and resolve the problem in the end. Follow the steps explained below.

Step 01: Clear Your Browser Cache

You must clear your browser cache first whenever you experience a problem with your WordPress site. Because the browser’s cache and cookies often don’t allow the website to function properly. To clear the cache of your Google Chrome browser:

  • Click on the three-dotted icon from the top-right corner of your Google Chrome window.
  • Then, navigate to More Tools > Clear Browser Data.

Shortcut key: Ctrl+Shift+Del (Windows) / Shift+Cmd+Back (Mac)

How to Clear the Brower Cache
  • Tick-mark the things you want to delete.
  • Click on the button Clear Data.

Clearing the browser cache may bring your website back to its normal state. Reload your website and check its current status. If it doesn’t return to normal, try the next approach.

Step 02: Disable All the Extensions

WordPress users use various extensions on their browsers to facilitate web-related tasks. Often these extensions may cause plugin conflict to your WordPress site. So, remove/disable all these extensions and install/activate them one by one to find the conflicting ones. To remove extensions:

  • Click on the extension icon on your browser window.
  • Click on the three-dotted icon next to the extension you want to remove.
  • Scroll down to the Remove from Chrome option and click on it.

Step 03: Update to the Latest Version of WordPress

To keep the WordPress eco-system bug-free, developers try to come up with updated versions of plugins and extensions regularly. Again, most plugins require the latest version of WordPress to function smoothly. Some of your plugins may conflict if you don’t have the latest WordPress version installed.

In the following way, you can update to the latest WordPress version.

  • Navigate to Dashboard > Updates.
  • Click on the button Update to version.

Step 04: Deactivate All the Plugins

Already we said, many WordPress plugins aren’t compatible with each other. For example, AliDropship is a great dropshipping plugin. But it’s not compatible with WooCommerce. Installing two of them can cause serious conflict to your site. Similarly, if you install Yoast and Rank Math SEO both, none will work.

You will find countless examples of such plugins online. Besides, bug(s) in a plugin can affect the entire website. It mostly happens if you use the null versions and developers don’t update the plugin for over three months.

To identify the faulty plugin, deactivate all the installed plugins and reactive them individually afterward.

  • Go to your WordPress dashboard.
  • Navigate to Plugins > Installed Plugins.
Go to Plugin Section to Deactive All the Installed Plugins
  • Tick mark the plugin check box from the top or bottom.
  • It will select all the installed plugins automatically.

So, choosing the right one for your site will be easy. If you still don’t find any conflict by now, you must try the default WordPress theme as a last resort.

Step 05: Activate the Default WordPress Theme

Conflicts between themes and plugins are nothing new in the WordPress eco-system. There are many WordPress themes that are built for particular plugins. For example, if you have AliDropship original plugin installed, Astra, Divi, Generate-Press, etc., popular themes won’t work on your site.

Because these themes are compatible with the WooCommerce-powered plugins only. You have to activate the default WordPress theme to detect whether your installed theme is causing the conflict. As of today, when we are writing this blog, Twenty Twenty Two is the official default theme of WordPress.

Here is how to set the default theme for your site.

  • Navigate to Appearance > Themes.
  • Click on the Active button of your default theme.

If your website returns to its normal state, then be sure there is a conflict between your web theme and plugin(s). Then, you need to change your theme or plugin and select the mutually compatible ones. Next, you can visit WP Hive to find the right theme for your website.

Method 02: How to Check and Fix WordPress Plugin Conflict Using a Plugin

Doing plugin conflict tests manually is a long process that can kill much of your time. There are some site health checker plugins by which you can identify conflicting issues and evaluate the health status of your site. Health Check & Troubleshooting is a great plugin you can use.
