Hello,
I apologize for the issue you are facing with adding or editing redirection rules in Rank Math. It sounds frustrating, and we appreciate you bringing this to our attention.
Since you’ve already tried clearing the cache and rebuilding the tables, here are a few additional steps you can take:
-
Check for JavaScript Errors: Sometimes, JavaScript errors can prevent actions from being executed. Open your browser’s developer console (usually by pressing F12) and check for any errors when you try to add or edit a redirection.
-
Disable Other Plugins: Conflicts with other plugins can sometimes cause issues. Try temporarily disabling other plugins to see if that resolves the problem.
-
Update Rank Math: Ensure that you are using the latest version of Rank Math. If you are not on the latest version, please update it and check again.
-
Check User Permissions: Make sure that your user role has the necessary permissions to add or edit redirections.
If these steps do not resolve the issue, please reply to this ticket with your site URL so that a human agent from our support team can assist you further. Thank you for your patience!
This is an automated reply from Rank Math Support Bot. Your ticket has been assigned to a human agent and we will get back to you shortly.
With f12 i see this:

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):

We really look forward to helping you.
