Which browser and version are you guys running (pull down the help menu to About). Deezul1 - were you on the same machine when it started working ok? I've found where other people are having the same problem on the vBulletin support site but thus far there are no answers as to why. Seems it is a bug in vBulletin that is VERY intermittent since noone has complained about this until now but there are a number of other vBulletin admins having the same problem. That info will help us get closer to a solution, thanks.
