No prefix [GroupManager for 1.8.1]

I checked and it all seemd well but I'm having no prefix, permissions are good tho.
IChat: handle-me: true
date-format: HH:mm:ss
message-format: '+iname: +message'
me-format: '* +name +message'
iname-format: '[+prefix+group+suffix&f] +displayname'
;]

Oh nvm fixed ^_^

-Edit: not fixed, no prefixes very fucked up.
