I'm making a new server and I want to have ranks, so I download this plugin called "GroupManager". I restarted the server, went InGame and wrote /mangadd Rookie and it said that the group was created. After wrote in the chat and had no prefix or nothing came out when i wrote the command. I also set prefix on the rank. I dont really know what is the problem with this plugin, I also checked PEX and bPer.. had the same problem. I have one world and its called by default 'world'. Can someone help me please? Thanks Pastebin of my groups: https://pastebin.com/y7PCjdVR
