SOLVED Hey everyone. So, I've been working with groupmanager and theres currently some bugs with it for me. NOTICE: I did update to the latest version of groupmanager and craftbukkit Groupmanager wont update with new permissions. Some permissions doesn't work in some worlds. A prefix/suffix wont load in some worlds. Theres nothing wrong with the groups.yml or users.yml file, but it seems to not work. Heres an example of a group.yml which doesn't work: Spoiler (Move your mouse to the spoiler area to reveal the content) Show Spoiler Hide Spoiler # Group inheritance # # Any inherited groups prefixed with a g: are global groups # and are inherited from the GlobalGroups.yml. # # Groups without the g: prefix are groups local to this world # and are defined in the this groups.yml file. # # Local group inheritances define your promotion tree when using 'manpromote/mandemote' groups: Owner: default: false permissions: - '*' - scavenger.scavenge inheritance: - head-admin info: prefix: '&1[Owner] ' build: true suffix: '' Member: default: true permissions: - BattleKits.sign.use - BattleKits.use.Archer - BattleKits.use.Derp - BattleKits.use.Knight - BattleKits.use.Ranger - BattleKits.use.Tank - BattleKits.use.TheNoob - essentials.balance - essentials.balancetop - essentials.delhome - essentials.mail - essentials.msg - essentials.r - essentials.spawn inheritance:  info: prefix: '&e' build: true suffix: '' Moderator: default: false permissions: - BattleKits.use.Barbarian - BattleKits.use.Pyro - essentials.ban - essentials.jail - essentials.kick - essentials.mute - essentials.repair - essentials.sethome.multiple - essentials.sethome.multiple.diamond - essentials.tempban - essentials.tp - essentials.unmute inheritance: - member info: prefix: '&5[Mod] ' build: true suffix: '' Admin: default: false permissions: - essentials.feed - BattleKits.use.Barbarian - BattleKits.use.Pyro - essentials.fly - essentials.godmode - essentials.hat - essentials.repair - essentials.repair.armor - essentials.repair.enchanted - essentials.sethome.multiple - essentials.sethome.multiple.obsidian - essentials.socialspy - essentials.tp.others - essentials.vanish inheritance: - moderator info: prefix: '&4[Admin] ' build: true suffix: '' Donator: default: false permissions: - BattleKits.use.Barbarian - BattleKits.use.Pyro - essentials.hat - essentials.kit - essentials.kits - essentials.sethome.multiple - essentials.sethome.multiple.lapiz inheritance: - member info: prefix: '&1[Donator] ' build: true suffix: ''
