Hello,
There has to be a plugin conflict with the Rank Math, Since you are saying you are unable to test the plugins, 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):
https://wordpress.org/plugins/wp-security-audit-log/
We really look forward to helping you.
Hello,
I have updated the sensitive data as requested. Can you please check further?
Also thank you for such a quick reply!
Thank you.
Hello,
Thanks for your reply.
We noted the issues with links in our previous update and we have already released an update with the fix.
I visited your website’s admin area and found that an update is pending for Rank Math:

Please update the plugin and see if the issue gets fixed.
Let us know how that goes.
Thank you.
Hi! I updated it and works perfectly. Thank you so much for your quick response.
I have a couple of blogging courses and used to recommend Yoast but have tested out RankMath enough to recommend that. Thank you again!! Great service.
