You know the plugin Permissionsbukkit? http://forums.bukkit.org/threads/ad...2k-official-default-groups-plugin-1240.26785/ I have been using this all the time, but today, I think it got bugged. I tried adding a new permission and then NOTHING worked anymore! No one had their permissions anymore, while everything is still normal in the config file. Even defaults (who normally don't have permission to build) can build wherever they want! The plugin itself is still active though (not disabled or something) but everythings messed up! The number of spaces I used in the config are all right, but still nothing works! I did not use tabs at all! (what normally will mess up the config) Things I tried out and which didn't help me out: Restarting server. Rebooting PC Regenerating the config file. Reinstalling the plugin. Reinstalling craftbukkit. Regenerating server properties. Disabeling ALL the other plugins and run this plugin only.
