Split: Custom Permalinks Not Working When Rank Math Active

Hello,

Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.

I split your reply into a new ticket so we can ask few more details with regards to your issue.

I tried replicating your issue from my end but I wasn’t able to as the permalink structure same as yours seems to be working just fine.

We might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress login 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.
