options < show all settings < error when updating a setting

I did a little searching on vbulletin.com for that error, and I found it a couple times, and both times it was caused by a mod. What you can do is try going to each group separately and hit save until you figure out which group is causing the problem. If we guess that it's a mod, then you'll probably want to start with any groups that are added by mods.
