server wide message at the top of screen

hey, it’s my first time running an garrysmod server, so i decided to buy a darkrp server off of some guy.
how would i go around removing this?
sorry for the noob question. ):
also, i’m getting like a double post thing

player1: hi
DEAD player1: hi

anyone know how to fix these?

So you bought DarkRP?

If you want to remove this you’re obviously going to need to find it… And there is no way we can help you without the code.

My friend did, he bought the server because it was decently populated and he’s paying for hosting for 2 months.
I was just wondering if there’s a specific file where it’s held or something.

I’m sure there is, as I said you’ll need to supply us with that.
