On one of my sites, I have two phpBB2 (release 2.0.22) message boards. I was looking at the cpanel file manager for the site, and just noticed that a few sub directories in each of them were set with permissions at 777. I know for sure that I had those folders set at 755. This kindof freaked me out. I checked the contents of each of them, did not see any "extra gifts" planted there, and changed the permissions back to 755.
The site was on a server that was migrated to TCH NOC last weekend, and after the migration I noticed that some old MYSQL databases that I had previously deleted reappeared (I noticed this on a site that was migrated this weekend as well). I wonder if perhaps the same phenomenon relates to the folder permissions, since at one time (several months ago), those sub directories had been set to CHMOD 777.
