Ok so im running a tekkit server and whenever i set up group manager prefixes they dont work unless i type /afk in game then it pops up with the colour ive tried download every different version of essentials group manager but nothing seems to work
Could you post your server log? It could help us identify the issue as it sounds like it could possibly be Tekkit or another plugin interfering. Also, do you have a plugin that can recognize prefixes such as HeroChat, EssentialsChat, or ChatManager?
