Message: Seems like your site URL has changed since you connected to Rank Math

Hello,

We apologize for the issue you are facing with the message regarding your site URL. To resolve the warning that states "Seems like your site URL has changed since you connected to Rank Math," please follow these steps:

1. Ensure You Are Using the Latest Version of Rank Math: Make sure that your Rank Math plugin is updated to the latest version. You can check for updates in your WordPress dashboard.

2. Check Your WordPress URL and Site URL: Navigate to WordPress Dashboard → Settings → General and ensure that both the WordPress Address (URL) and Site Address (URL) are the same. They should match for a proper connection.
   

3. Disconnect and Reconnect Your Rank Math Account: If the URLs match, try disconnecting your Rank Math account and then reconnecting it. You can do this by going to Rank Math SEO → Dashboard → Help and selecting Disconnect Account.
   

4. Clear Cache: If the warning still appears, please clear your browser cache, website cache, and any site-level cache before attempting to reconnect.

5. Add a Filter (if necessary): If the issue persists, you can add the following filter to your website to bypass the URL check:

   /**
   * Filter whether we need to check for URL mismatch or not.
   */
   add_filter( 'rank_math/registration/do_url_check', '__return_false' );

   You can refer to our guide on adding filters if you need assistance with this step.

If you continue to experience issues after following these steps, please reply to this ticket with your site URL, and a human agent from our support team will assist you further. Thank you for raising this concern!
