Hello,
Thank you for contacting us. We apologize for any inconvenience this issue may have caused.
We released a quick Beta update you can try to see if that helps.
Please enable the Beta update by following this:
https://rankmath.com/kb/version-control/#beta-updates

If you are unable to see an update, please clear Rank Math’s transients from:
WP Dashboard > Rank Math > Status & Tools > Database Tools > Remove Rank Math Transients > Remove transients

Please clear the caches, server, and WordPress after updating.
You can disable the Beta updates once you update to the latest version and if the issue is fixed.
We are here to assist. Thank you.
Hello. I had to roll back to the previous version of your plugin because another fatal error occurred today. I put the error log in the sensitive data section.
Hello,
In this case, 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,
I have updated the sensitive data as requested. Can you please check further?

Hello,
We apologise for the delay in getting back to you.
It seems you skipped including your site’s login URL in the sensitive data section.
Kindly share that with us also, so we can investigate this issue further.
Thank you.

Hello. I just removed DefenderPro due to recaptcha and login problems so you don’t need a separate login page anymore.

Kindly share the affected site’s URL with us.

I was just using the Docket Cache Plugin flushing Transient Cache and I got another critical Fatal Error preventing access to my website and to the WP Admin dashboard so I had to change the name of the Rank Math directory to deactivate it. I put the fatal error message in the sensitive data area. Have you discovered the problem yet. I gave you login credentials a week ago. Please help. Thank you! https://collectiblesandmoreinstore.com
Hello,
Since activating Rank Math will cause a fatal error on your website, not allowing us to access the dashboard itself, we may need to get access to your FTP.
Please share your website’s FTP login in the Sensitive Data section as well so we check the issue closely.
Looking forward to helping you.
