Forum Usergroup settings not working

[محروم.كوم]

When I change a setting in Usergroup Manager, it creates a duplicate Custom Usergroup, but the setting in the original Usergroup isn't changed. Just updated to vb4, no mods installed (I uninstalled them all before the upgrade).

Identical to http://www.vbulletin.com/forum/showthread.php?301560-Cannot-edit-usergroups&p=1702626 , only I have jiggered my suhosin settings and it's still not working. Help!
