My name is Jonathan and I've been with Xenforo for a good 2 and a half years. Over the last year, I have opened 2 forums which keep being defaced. They change the PAGE_CONTAINER template mainly and I wonder, how do they do this? My file permissions are not set to 077 because I know that those permissions are not safe especially for the data files. I used CPanel for those forums and I was constantly being defaced. Even if I reverted my templates, the forum was ruined. At this moment, I plan on opening a brand new forum using Nginx and a VPS. I however need help regarding the defacing issue and how I can prevent it.
If anybody could help me, it would be greatly appreciated.
