Unable to connect website

Hello,

Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.

Please head over to WordPress Dashboard > Settings > General and make sure there are no mismatches in the WordPress URL and Site URL in those options.

After that, please try disconnecting and reconnecting your Rank Math account to see if this resolves your issue.

If the issue still persists, you can try adding the following filter on your website and then try reconnecting to your account again.

add_filter( 'rank_math/registration/do_url_check', '__return_false' );

Here is a guide you can follow to add the filter:

Let us know how it goes. Looking forward to helping you.

Thank you.

Hello,

We might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.

Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:

https://wordpress.org/plugins/temporary-login-without-password/

You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

We really look forward to helping you.

Hello,

Thank you for your patience.

Yes, the account reconnection should be done with the user with administrator capabilities:

Also, if you’re using a multisite environment, then you may need to follow our guide here to properly activate the Rank Math plugin:
