Essentials Chat Formats Not Working

I have been trying all day to get my essentials chat group formats to work but the messages don't change color when i try to get it to work!
Please help

Config:

chat:

# If EssentialsChat is installed, this will define how far a player's voice travels, in blocks. Set to 0 to make all chat global.
# Note that users with the "essentials.chat.spy" permission will hear everything, regardless of this setting.
# Users with essentials.chat.shout can override this by prefixing text with an exclamation mark (!)
# Users with essentials.chat.question can override this by prefixing text with a question mark (?)
# You can add command costs for shout/question by adding chat-shout and chat-question to the command costs section."
radius: 0

# Chat formatting can be done in two ways, you can either define a standard format for all chat.
# Or you can give a group specific chat format, to give some extra variation.
# For more information of chat formatting, check out the wiki: http://wiki.ess3.net/wiki/Chat_Formatting

#format: '<{DISPLAYNAME}> {MESSAGE}'
#format: '&7[{GROUP}]&r {DISPLAYNAME}&7:&r {MESSAGE}'

group-formats:
# Default: '{WORLDNAME} {DISPLAYNAME}&7:&r {MESSAGE}'
# Admins: '{WORLDNAME} &c[{GROUP}]&r {DISPLAYNAME}&7:&c {MESSAGE}'
owner: '{DISPLAYNAME}&f:&6&l{MESSAGE}'
head-admin: '{DISPLAYNAME}&f:&4&l{MESSAGE}'
admin: '{DISPLAYNAME}&f:&4&l{MESSAGE}'
default: '{DISPLAYNAME}&f:&0{MESSAGE}'
moderator: '{DISPLAYNAME}&f:&5&l{MESSAGE}'
helper: '{DISPLAYNAME}&f:&3&l{MESSAGE}'

 

Did you restart? Because it's not working for me sometimes when I reload.

Also are you sure you don't use any other chat plug-ins or plug-ins with chat formats? Like Towny.

 

If you have factions installed you need to change some stuff in the factions config which you can find in Server Name\mstore\factions_mconf open the instance file with notepad or any program of your choice.
Find chatSetFormat and set it to false and that should fix the problem.
