Yes, we can access the site just fine. Admin, users, change logos, do everything with the script except upload videos (which is the main function of this script).

We were running PHP 5.2.2 and we even downgraded to see if that would help since most are running PHP 4.x, and it didn't.

Actually we can upload videos, they do manage to get renamed and placed in the video directory, but that's it, the error occurs and no thumbnail or anything else works that point. The video shows on the site but the player won't play it (like it's not there) and no thumbs etc.

We could troubleshoot this better if upload.php wasn't encoded, but it is so that doesn't help. Obviously there is little support for this script due to it's low cost.
