Hello,
I apologize for the issue you are facing with your Rank Math setup. It sounds like there may be a configuration issue causing the site URL to revert to the Hostinger domain.
Here are a few steps you can take to ensure that your website is correctly set up:
-
Check WordPress Address & Site Address: You’ve mentioned that you’ve already checked this, but it’s crucial to ensure that both the WordPress Address and Site Address in Settings → General are set to `http://example.com.

-
Edit .htaccess File: If the issue persists, you may need to add redirection rules to your .htaccess
file to ensure that all traffic is directed to your desired URL. You can edit the .htaccess
file directly from the Rank Math dashboard:
-
Clear Cache Again: After making these changes, clear your website cache again and check if the issue is resolved.
If you continue to experience problems, we recommend replying to this ticket with your site URL so that a human agent from our support team can assist you further. Thank you for raising this concern, and we hope to help you resolve it soon!
