Hello,
We apologize for the issue you’re facing with the persistent popup regarding your site URL. This can happen if the WordPress URL and Site URL are not matching. Here are some steps you can take to resolve this:
-
Check Site URLs: Go to your WordPress Dashboard → Settings → General and ensure that both the WordPress Address (URL) and Site Address (URL) are the same.

-
Disconnect and Reconnect: If the URLs match, try disconnecting your Rank Math account again by going to Rank Math SEO → Dashboard → Help and selecting Disconnect Account. After that, reconnect your account.
-
Clear Cache: If the warning still appears, please clear your browser, website, and site-level cache before attempting to reconnect again.
-
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' );
You can refer to our guide on adding filters for more details.
If you continue to experience this issue after trying 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 bringing this concern to our attention!
