Minecraft Server Issue

[Reposting here, because where I posted it initially is inaccessiblle]
Okay, so I've been having this issue ever since I started working on the server, even before I applied to host it under icemod, and I've actually been trying to avoid asking for help, but I just cant seem to fix it.

The plugin is essentialsChat, and I'm using Essentials GroupManager for the permissions, and under the chat formatting there should be a variable that shows the user's rank before their name by having {GROUP} there, but that never seems to work.

It started off by only showing (default) instead of the player's group, but now it only says {GROUP} if I put it back, so I've actually been excluding that function from the chat formatting.

What I need, is either a solution or a replacement to the chat plugin.

 

You're probably looking in the wrong file. Add me on steam and if 1day or someone could vouch for me i'll have a look.
