Hello,
Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
Can you please try to only enable the Rank Math plugin and disable the rest? See if the issue still persists. You may follow this handy troubleshooting guideline so your users will not be affected: https://rankmath.com/kb/check-plugin-conflicts/
Only the site admin would know and your users won’t be affected by this troubleshooting.
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.
Well, it seems that after updating the plugin, the issue has been resolved.
