Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
We’ve checked your page and it seems like the errors are only appearing when you’re logged in because we’re not able to see those errors. Could you please temporarily deactivate the Rank Math plugin and check this page again if the errors are still appearing or not? Don’t worry, you’ll not lose your settings because they are stored on your database.
If the errors disappear after deactivating the Rank Math plugin then 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):

Looking forward to helping you.
Thank you.
