Resolving Common Site Kit by Google Plugin Conflicts and Issues

Many WordPress users rely on Site Kit by Google to seamlessly integrate Google services like Analytics, Search Console, and AdSense. However, like any powerful plugin, it can sometimes conflict with other themes or plugins, leading to a range of frustrating issues. Based on community reports, this guide covers the most common problems and their solutions.

Common Symptoms of Site Kit Conflicts

Users often report the following issues after installing or updating Site Kit:

  • White screens, slow admin pages, or critical errors that crash the site.
  • JavaScript errors in the browser console, such as 'Maximum call stack size exceeded' or 'Marionette is not defined'.
  • Functionality breaks in page builders (like Elementor or Divi), contact forms (like Contact Form 7), or e-commerce features (like WooCommerce cart updates).
  • Strange text appearing in the footer or other parts of the site.
  • The plugin getting stuck during setup or disconnecting after updates.

Why Do These Conflicts Happen?

Conflicts usually arise not from a bug in Site Kit itself, but from how it interacts with other code on your site. Common causes include:

  • JavaScript Conflicts: Site Kit loads its own scripts to power its dashboard and admin toolbar. If another theme or plugin loads an incompatible version of a JavaScript library (like Backbone.Marionette), it can cause errors.
  • Optimization Plugins: Caching, minification, and asset optimization plugins (e.g., WP Rocket, LiteSpeed Cache, WP Fastest Cache) can sometimes break Site Kit's scripts by combining or altering them incorrectly.
  • The Admin Toolbar: The 'Display relevant page stats in the Admin bar' feature is a frequent culprit in conflicts with frontend elements and page builders.
  • Management Tools: Using third-party management services like ManageWP to update Site Kit can occasionally cause it to disconnect.
  • Outdated Code: Older themes or plugins may use functions or code structures that are incompatible with modern plugins like Site Kit.

Step-by-Step Troubleshooting Guide

Before you begin, it is highly recommended to create a full backup of your site.

1. Perform a Basic Conflict Check

The first step is to identify if the issue is a conflict and what is causing it.

  1. Enable Troubleshooting Mode: Use the Health Check & Troubleshooting plugin. This allows you to deactivate all plugins and switch to a default theme (like Twenty Twenty-Four) only for your user session, without affecting visitors.
  2. Check with a Default Theme: In troubleshooting mode, switch to a default WordPress theme. If the issue resolves, the conflict is with your theme.
  3. Check with Plugins: While still in troubleshooting mode, enable only Site Kit. If the issue is gone, begin enabling your other plugins one-by-one, checking after each activation to see which one causes the problem to return.

2. Disable the Site Kit Admin Toolbar

A significant number of reported conflicts, especially those affecting page builders and frontend menus, are resolved by disabling this feature.

  1. Go to Site Kit > Settings > Admin Settings.
  2. Uncheck the box for 'Display relevant page stats in the Admin bar'.
  3. Save changes and see if the issue is resolved.

3. Check Caching and Optimization Settings

If you use a caching plugin, try the following:

  1. Temporarily clear all your cache (page, browser, and CDN if applicable).
  2. Temporarily disable features like JavaScript minification, combination, or deferred loading.
  3. See if the problem disappears. If it does, you can often resolve the conflict by adding Site Kit's script files to the exclusion lists in your optimization plugin's settings. Common scripts to exclude include those containing 'google' or 'sitekit' in their filename.

4. Reset Site Kit

If the plugin is stuck, disconnected, or behaving erratically, a reset can often help.

  1. Go to Site Kit > Settings > Admin Settings > Reset Site Kit.
  2. Confirm the reset. This will disconnect the plugin from your Google account and clear its settings.
  3. Set up the plugin again from scratch.

5. Browser and Server Checks

  • Browser Console: Always check your browser's JavaScript console (F12) for any red error messages when the problem occurs. These errors provide vital clues.
  • Site Health Info: The Site Kit by Google support team often requests Site Health information to diagnose issues. You can find this at Tools > Site Health > Info in your WordPress dashboard. This data provides details about your server environment that can be crucial for troubleshooting.

Conclusion

Most conflicts involving Site Kit by Google can be resolved through systematic troubleshooting. The process almost always involves identifying the other piece of code—be it a theme or another plugin—that is causing the conflict and then adjusting settings accordingly. Starting with the Health Check plugin and disabling the admin toolbar feature are the most effective first steps for most users.
