Display name conflict

Hello,

i posted a topic similer to this but i didn't get any attention, so let me explain again

i have a new forum and i called my self "the lord", then i changed it to "GeoX", then i wanted to get back to the previous display name but it says "sorry but this name already benn taken", and there is NO other account with the name "The Lord"... BUT i have a group called "The Lord", so, is it why it ain't get change?!..and what's the might cause conflict between the display and the group name?!..thank you!

p.s: i've cheched the "censored usernames"..that display name is surelly not included

Wierd

Have you checked in the inactive users?
Also, try re-naming the group and then re-naming yourself

No Caihlem no other users ..only 4 users now (including me)
..okay i may try to change the group name, and if it works.we may make it as a new hint int the "tips & tricks" section

and thank you for helping
