Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
Can you please update your WordPress version to 5.6
and see if the fatal error goes away?
If the issue persists, 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.

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?
Thank you.
Hello,
Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
It looks like there have been some issues when Rank Math tries to update to the latest versions.
It is impossible for us to access your WordPress Dashboard at the moment because the fatal error is blocking access.
Can you please share your FTP access so we can manually disable the plugin and fix the issue?
We are looking forward to helping you.
Hello,
It seems like you have skipped at least 10 Rank Math updates and that is why this error is popping up.
Please share your WP logins so we can sort this for you.
Alternatively, you can delete the rank_math_version
row in your wp_options
table using phpMyAdmin or ask your web host to do that.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
I put the rank_math_version row in my wp_options to autoload “no”.
Now it works again and autoload is by it self changed to “yes” again.
IT works!!
Thanks a lot!!!
