Groupmanager Prefixes

I was playing around with my permissions file for groupmanager and the server started displaying both the name of the group and the prefix. How do i re-disable the showing of the actual name of the group?

My Permissions file:
http://pastebin.com/147QLKmd

 

Group Manager will only display the prefix. I'm guessing you have another plugin that controls chat other than Essentials Chat? Could you list your plugins please?

 

Recently added plugins:
headbounty
masterpromote
mcmmo
autoconfiscate

 

well, what about the other plugins you have, not just recent.

 

also paste essentials config.yml.

 

Thanks for the help! The problem was that my essentials config file was actually empty.
