Error: Plugin Conflict Error

17 views
Updated February 28, 2026

Quick Fix

Deactivate all plugins, then reactivate one by one until the error reappears. Once found, update or replace the conflicting plugin.

What it Means

The Plugin Conflict Error happens when two or more WordPress plugins use the same functions, hooks, or database tables, causing a clash. WordPress stops loading to prevent site crashes, displaying this error.

Possible Causes

  • 1
    Duplicate function names
  • 2
    Conflicting hooks or filters
  • 3
    Database table conflicts
  • 4
    Outdated plugin versions

How to Fix

    Step-by-Step Solutions

    1. Deactivate All Plugins

      Log in to the WordPress admin, go to Plugins > Installed Plugins, and bulk deactivate all plugins to clear the conflict.

    2. Reactivate Plugins Individually

      Enable plugins one by one, refreshing the site after each activation to see when the error returns.

    3. Identify the Conflicting Plugin

      The plugin that triggers the error is the culprit. Note its name for further action.

    4. Update or Replace the Plugin

      Visit the plugin’s page to check for updates. If none, look for an alternative plugin that offers similar features without conflicts.

    5. Check for Hook Conflicts

      If you’re a developer, inspect the plugin code for add_action or add_filter calls that might clash with others.

      grep -R "add_action" /wp-content/plugins/

    Commands You Can Try

    wp plugin deactivate --all
    wp plugin activate plugin-name
