I'm sure I have!
I have entered the code as requested. However, no users are getting the new little flag.
If I change the setting to group 2 or 3 which would be for Moderators, or Users, then the flags are applied as I would expect.. but using any group that has been created, it ignores it, and you do not see the flag.
I have tried all the steps multiple times, and the same thing happens time and time again.
I have no other hacks installed on version 6.2.3.
It is now set to "5" which is for the group I have created, I have added some users to this group, and there are no flags.
Totally lost now..
