Resolving Conflicts Between Redux Framework and the WordPress Editor

16 threads Sep 16, 2025 Plugin → Redux framework

Content

Many WordPress users who rely on the Redux Framework for theme and plugin options encounter issues related to the WordPress editor, particularly the Gutenberg block editor. These conflicts can manifest as strange warnings, missing features, or unexpected behavior. This guide will help you understand why these conflicts happen and provide the most common solutions to resolve them.

Common Symptoms of Editor Conflicts

Based on community reports, issues often present themselves in the following ways:

  • PHP warnings mentioning array_intersect_key() or errors in class-wp-rest-server.php after a WordPress update.
  • The Yoast SEO slug field appearing empty on pages.
  • Notices stating that Gutenberg is disabled due to another plugin (like Classic Editor).
  • Redux-specific page templates (e.g., "Redux Canvas") disappearing from the template dropdown.
  • Empty style tags being output on the front end.

Why Do These Conflicts Happen?

The core of these issues is typically a compatibility problem between Redux Framework's features and the WordPress editing environment. The Redux Framework team has integrated template libraries and other tools designed to work with Gutenberg. When another plugin, like the Classic Editor or a Gutenberg-disabling plugin, alters the editing environment, it can create unexpected interactions. Furthermore, significant WordPress core updates (like the jump to version 5.6) can change how APIs function, temporarily breaking compatibility until the Redux Framework team can release an update.

How to Troubleshoot and Resolve These Issues

1. Identify the Conflict

The first step is always to perform basic conflict testing. This is the most reliable way to identify the culprit.

  1. Deactivate all plugins except Redux Framework.
  2. Switch to a default WordPress theme (like Twenty Twenty-One).
  3. Check if the problem persists. If it is gone, reactivate your plugins one by one, checking each time to see which one causes the issue to return.

2. Resolve Common Plugin Conflicts

As seen in the sample threads, a very common conflict is between Redux and plugins that manage the editor experience.

  • Classic Editor / Disable Gutenberg Plugins: If you use a plugin to disable Gutenberg, you may see notices or strange behavior. You can often simply dismiss the notice, as the Redux Framework template library is an optional feature. If the conflict causes functional problems (like empty Yoast slugs), you may need to choose between using the Classic Editor plugin or the Redux template features.

3. Check for and Apply Updates

Many conflicts arise after a major WordPress core update. The Redux Framework team is typically quick to address these issues. Ensure you are running the latest version of the Redux Framework plugin, as it will contain the most recent compatibility patches.

4. Hide Unnecessary Features (For Developers)

If you are a theme or plugin developer using Redux and your clients do not need the template library, you can hide the interface elements to prevent confusion. You can use custom CSS to remove the template button:

function hide_redux_button() {
  echo '<style>
 .redux-templates-insert-library-button {display: none;} 
  </style>';
}
add_action('admin_head', 'hide_redux_button');

5. Review Error Logs

If you are seeing PHP warnings or notices, enable WordPress debugging and check your debug.log file. The specific error message can provide vital clues and should be referenced if you need to seek further help from the community.

Conclusion

In most cases, conflicts between Redux Framework and the WordPress editor are not due to a bug in Redux itself, but rather an interaction with another plugin or an outdated version. By methodically testing for conflicts, keeping everything updated, and optionally hiding features you don't use, you can quickly resolve these issues and get back to building your site.
