Hello,
We apologize for the inconvenience you’re facing with the error message “Seems like your site URL has changed since you connected to Rank Math.” This issue can be resolved by following a few steps.
First, ensure that you’re using the latest version of Rank Math.
Next, check that the WordPress URL and Site URL are the same. To do so, navigate to WordPress Dashboard → Settings → General and check that both URLs are the same.

If both URLs do not match, you might receive this notice. Both URLs should match for a proper connection.
After that, please try disconnecting and reconnecting your Rank Math account again to see if this resolves your issue.
If the warning still shows up, please disconnect your Rank Math account and clear your browser, website, and site-level cache before reconnecting.
However, if the issue persists, you can add a filter on your website and reconnect to your account. You can refer to our dedicated guide to add the filter to your site.
/**
* Filter whether we need to check for URL mismatch or not.
*/
add_filter( 'rank_math/registration/do_url_check', '__return_false' );
And that’s it! The plugin should now be able to stay connected without any issues.
If you still have questions regarding this warning or face any problems while connecting to your site, feel free to contact our dedicated support team. We’re available 24/7, 365 days a year.
I hope this helps! Let us know if you need further assistance.
