Why are you using Permissions 2? That is way outdated and no longer supported by the RB.

 

I just used the latest Essentials plugin from http://dev.bukkit.org/server-mods/essentials/ . I've tested by only having Essentials in the plugins folder and it seems Essentials is the thing causing the problem for me.

EDIT: It seems that essentials together with bPermissions is causing the problem...

EDIT: SOLVED sort of. For some reason if I put a new bPermissions plugin with an Essentials it causes that error. But when I added worldedit, something made it go back to normal.

 

Still wanna answer to my question.

 

I dont even think I touched anything called permissions 2 before. Sorry I'm clueless
