However I have an addon that allows me to click a link & "login" as another user and by doing that I dont get this error, it seems to only affect admin accounts for some reason. This started happening after I transferred the database to a new host.

I'm not quite sure what's going on there..... but your timeout isn't set. I see you on your forum as of just a few minutes ago, but other members from earlier today and someone from last night. http://vgchat.info/forum/online.php?...e&pp=50&page=1

MySQL error 2006 usually relates to "SQL timed out because it couldn't gather what you asked for in time" -- essentially, your SQL was sent to pick a whole apple orchard when you asked for the apples from one tree. Set your timeout to something like 15 or 20 minutes and see if you still get the SQL error.
