When trying to edit and save changes to certain templates such as navigation and messages I receive the following popup error and am unable to make any changes.
After some research the error seems to be typically caused by mod security so I contacted my host. They told me mod security wasn't interfering and gave me this error from our logs saying that the problem seems to be on xenforos side.
Some of the templates I'm trying to edit are ones I've successfully edited in the past. I recently upgraded my xenforo from 1.2 to 1.5.7, as well as my style and add ons.
The following error occurred: Forbidden You don't have permission to access /pvp/pn/admin.php on this server.
