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

Hello,

I apologize for the inconvenience you’re experiencing with connecting your website to Rank Math. I understand that you received a message stating that your site URL has changed since you connected to Rank Math, and when you clicked on the reconnection link, it showed your website’s IP address instead of the correct URL.

To resolve this issue, please follow these steps:

1. First, ensure that you are using the latest version of Rank Math. You can check for updates in the WordPress dashboard under “Plugins” and update Rank Math if necessary.

2. Next, check that the WordPress URL and Site URL in your WordPress settings are the same. To do this, go to your WordPress Dashboard, navigate to Settings > General, and verify that both URLs match.

3. If the URLs do not match, please update them to be the same.

4. After verifying the URLs, try disconnecting and reconnecting your Rank Math account. You can do this by following the instructions in this knowledgebase article.

If the issue persists after following these steps, please add the following filter to your website and then reconnect to your Rank Math account:

/**
 * 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 dedicated guide on adding filters to your site for more information.

If you have any further questions or encounter any difficulties, please don’t hesitate to contact our dedicated support team. We’re available 24/7 to assist you.

Thank you for your patience and understanding.

Best regards,
Rank Math Support
