Prefixes dont show in my chat! Help!

Hi, I have a problem, Im setting up a server, and the prefixes of PermissionsEx didnt work, it worked in the past, but not now, and I dont know why.
(PEX) Permissions.yml file: http://pastebin.com/MdPkRqmf
(Chatmanager) config file: http://pastebin.com/JPazq7hH
(Plugins): Orebfuscator, WorldEdit, VisitCounter, PorteCoulissante, PvPTime, SafeExplosions, Vault, PermissionsEx, Stargate, Multiverse-Core, iConomy, AuthMe, CoreProtect, MineMaze, PvPTitles, BKCommonLib, Lockette, ClearLag, DeathMSG, MobArena, FoundDiamonds, Essentials, AntiPvPLogger, Jobs, ChatManager, EssentialsSpawn, RecipeManager, Factions, AntiCheat

 

Remove all those suffix in your Pex file

 

But I dont have any suffixes set...

 

but, in your pex file at every group stands this: suffix: "

delete those

 

Ok, I did that, and doesnt work

 

can you repost your pex file?

and turn chatmanager to false and check if that works
