Plugin Help GroupManager error

Hey everyone!
I have a problem concerning groupmanager. Indeed, the error comes from groups.yml, because when i removed it from its folder, every commands were allowed. However, when i put groups.yml back in its folder, the error comes back. So, it means that the error comes from this .yml but after several look, i was not able to discern the error in question.
Here is my groups.yml : http://pastebin.com/NWy8U8VC
I need help! Thank you

 

@AeternaeDamnatio I suggest getting another version. I had this problem before so I got another version of the plugin and it works fine right now. Another thing you can do is keep the same verson, delete the 'GroupManager' folder, then restart the server. Then redo groups by only commands. Do not go to the config (At least on that version)!

 

I will try this, thank you !

@ZanctarianDevelopment But, the error doesn't come from my groups.yml ?
Here is my GroupManager folder, i don't know where the error is but, i know she is in group.yml in the lobby folder :
