It means that you probably extended JavaPlugin twice. Also if ou want specific answers you should also paste your code that's causing the problem or format it using the BBCode tags. You should instead of directly putting you StackTrace in the post, again format or paste it.
If you don't understand the moderator, administrator, eier e.t.c is because im norwegian and owns a norwegian server
"me.Emrik.Main" Could you refactor that to "me.emrik.prefixtab.Main", and also change the main in your plugin.yml to match this. Just try it out
