I do have vault and Essential chat

I have no idea what happen to your server all I can guest is that the guy you op did something with your server (and in the future don't op any one you don't know or trust)

When I make a prefix for a group and when i join it and say something in the chat my name is just red and it has no prefix someone help

When I try to use @p or any other one of these command I all way get Error:Player Not Found can anyone help me out?
