[solved] Bug 1.5.8 - vbBux vbPlaza Permissions don't appear in usergroup settings

Hello everybody,

I have a big problem since I have updated from 1.5.6 to 1.5.8. Actually the vbBux vbPlaza Permissions in usergroup settings don't appear and nobody can acces the vbplaza...

I have uploaded and reuploaded all files 2 times, reimported the product 5 times and done a "rebuilt bitfileds" 5-6 times too but nothing was changed, all other settings work well, only the permissions are not showing...

Anyway to fix that ?

Thanks you very much

Edit : I have solved the problem, if anyone encounter the same trouble I can give a little help ^^
