Also, /chatcolor doesn't work and when i do /help essentialschat, i get: Permissions manager is not accessable is the PermissionsEx plugin enabled? I've tried loads of things but just can't seem to get why it doesn't work. Thanks in advance guys!!

I think it might be an issue with my permissions file, but I can't seem to find it
