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

Hello, we apologize for the issue you are facing with the warning message regarding your site URL. This notice typically appears when the WordPress URL and Site URL do not match. Here are the steps you can take to resolve this issue:

1. Check Your URLs: Ensure that both the WordPress URL and Site URL are the same. You can do this by navigating to WordPress Dashboard → Settings → General and verifying that both URLs match.

   

2. Disconnect and Reconnect: If the URLs are correct, try disconnecting and then reconnecting your Rank Math account.

3. Clear Cache: If the warning still appears, please disconnect your Rank Math account and clear your browser, website, and site-level cache before reconnecting.

4. Add a Filter: 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' );

Following these steps should help resolve the warning. If you continue to experience issues, please reply to this ticket, and a human agent from our support team will assist you further.
