Hello,
We apologize for the issue you are facing with adding or editing redirections. The error message you mentioned, Uncaught TypeError: Cannot read properties of undefined (reading 'top')
, suggests that there might be a JavaScript conflict on your site, possibly caused by another plugin or theme.
To troubleshoot this issue, we recommend the following steps:
-
Open the Developer Tools Console: You can do this in Chrome by navigating to More Tools → Developer Tools and then clicking the Console tab. This will help you identify any additional errors that may be occurring.

-
Check for JavaScript Conflicts: If there are any errors in the console, they may indicate conflicts with other plugins or your theme. You can try deactivating other plugins one by one to see if the issue resolves itself.
-
Firewall Settings: Ensure that your firewall is not blocking any Rank Math files. If it is, you may need to whitelist them.
-
Check .htaccess File: Sometimes, issues can arise from redirects set in the .htaccess file. You can check this by navigating to WordPress Dashboard → Rank Math SEO → General Settings → Edit .htaccess. Make sure there are no conflicting rules there.

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 raising this concern, and we look forward to helping you resolve it!
Hello,
The issue here is that your Rank Math PRO plugin is outdated and doesn’t match the current version of the Free plugin.
We have gone ahead and fixed this issue by manually updating the plugin. The issue with adding a new redirection should now be resolved. Please check from your side.
