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.
Could you please share some of the affected URLs so we can check? You can add them in the sensitive data section

It is completely secure, and only our support staff has access to that section.
Meanwhile, after deactivating Rank Math, head over to your WordPress dashboard > Settings > Permalinks, then click the save button once.
Let us know how this goes.
Thank you.
