Bukkit

My problem is simple.
I installed to use Gringotts vault. And I have the plugin "essential"

But: Essential has an economic aspect. Can not be disabled. I even tried to disable the controls in relation to the economy, but nothing changes.

When I type the command / pl I also noticed that gringotts is noted in red. Is this an error signal? I have no error in my console.

nothing happens when I write on a board [vault] above a safe

Have you installed vault? If a plugin shows up in red it hasn't loaded properly.

Also check permissions.

I'm a bit behind on my issues... has it worked out for you?
