Mam mały (duży  :)) problem. Nie działa mi essentials chat. Zamiast tego co ustawiłem w konfigu:

############################################################
# +------------------------------------------------------+ #
# |                   EssentialsChat                     | #
# +------------------------------------------------------+ #
############################################################

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.
  # If set to the default chat format which "should" be compatible with ichat.
  # For more information of chat formatting, check out the wiki:

  format: '{GROUP} {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}'

  # If you are using group formats make sure to remove the '#' to allow the setting to be read.[/spoiler]

Podejrzewam, ze to multiverse core
wejdz w jego config i jesli masz 
  prefixchat: 'true'
to zmien na

  prefixchat: 'false'

a pozniej poustawiaj prefixy rang w essentials chat
