Something is wrong with my group manager plugin, I can't seem to find out what it is. Any help would be appreciated.

 

I May be wrong , im no expert at this but i think that u have done some mistakes in the language format in the config causing the error to occur....Umm by the way i can see at the end the command
manuaddsub baller pyronerd2....i think that ur supposed to write the playername and THEN the group.....Hope i helped
