Did not able to connect to Rank math Account

Hello,

Thanks a lot for your query and we are so sorry about the trouble this must have caused.

Please head over to WP > Settings > General.

Make sure both the URLs are correctly setup.

If that doesn’t work, we might need to take a closer look at the settings. Please include your WP logins in the designated Sensitive Data section.

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):
https://wordpress.org/plugins/wp-security-audit-log/

We really look forward to helping you.
