Solved PurePerms & PureChat NOT working?

So i have this pocketmine server with 30 something plugins and when ever i try to /setgroup ChoosyproDev (My username) Owner it dosent work. If i remove ALL the plugins EXCEPT for PureChat And PurePerms it WORKS?!?!?! But even if i put 1 plugin back into the plugins folder, It DOSEN'T work any more! Is this due to some plugins over writing PureChat/PurePerms? Plz Help Thx

 

U must say the error

 

Oops
So whenever i ONLY have pureperms and purechat in the plugins folder, I can get ranks to work. For example: [Owner] ChoosyproDev. But whenever i even add one other plugin, It will not show the ranks/prefix/suffix.

 

I think u must have some plugin relate to the chat. Please check again

 

I have the following plugins:
Advanced Kits
Always Spawn
AntiSpamPro
BankNotes
BuilderTools
BuycraftPM
CustomAlerts
EconomyAPI
EssentialsPE Dev-17
FormAPI
HungerGames
Invsee
MineReset
Mining Rewards
MysteryCrates
PerWorldChat
PiggyCustomEnchants
PiggyCustomEnchantsShop
Piggy Tutorials
Powertools
PureChat
PurePerms
SeeDevice
ShadowAntCheat
ShopUI-FormAPI-Working
Simplewarp
Skyblock
Slapper
StaffChat
TimeCOmmander
Worlds
ServerRanks
CombatLogger
TimeRanks
But plz note that if i insert ANY one of these plugins purechat/pureperms brakes.

 

i think it may be PerWorldChat

 

Got that noted. I will check it out.

 

Ok, I just deleted pocketmine and reinstalled all the plugins including Perworldchat and now it works! Thanks for your help! Much appreciated!
