Hello,

I'm getting a 403 Error when trying to change some forum permissions in forum management. I'm able to unselect Forum Open on any new forum or sub forum I create, but any previously created, when I try to select the same, I get the 403 error.

Edit to add I'm running 1.8.29

Can you ask your host if there's any error logs or security rules that are being triggered? Is unusual to be getting this sort of error when setting permissions specifically.

It was triggering ModSec rules. That's resolved now - thanks!
