Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
It seems like the tables to save redirections were not created for some reason.
In this case, please head over to your WordPress Dashboard > Rank Math > Status & Tools > Database Tools and click the Recreate Missing Database Tables button and see if that works for you: https://rankmath.com/kb/rank-math-status-and-tools/#recreate-missing-database-tools
Please note that some options are only available when you enable the Advanced Mode in Rank Math. If Database Tools is not showing, please switch to the Advanced Mode: https://rankmath.com/kb/switch-from-easy-to-advanced-mode/
Let us know how it goes. Looking forward to helping you.
Thank you.
