Hello,

Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.

Are you using a page builder on your site? If so, please share the name of the builder.

Meanwhile, if the changes are not getting saved, please check if you are using a Firewall as it may prevent saving the changes.

You can check this link for more information:

Let us know how this goes.

Thank you.

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:

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.
