Edit :

I found the problem here...Some people who have the vBIndex 2.0 hack installed, might want to check their usergroup.php file, around Line 35...

It should look like this :

// vBindex Edit
makeyesnocode("Can view vBindex?","canviewvbindex",1);
// vBindex Edit

However mine looked like this :

// vBindex Edit
makeyesnocode("Can view vBindex?","canviewvbindex,1");
// vBindex Edit

That made the Database error:)
