Edit package parameters security in FWM

[ichelly]

HI,

I have a problem in my Framework Manager while attempting to edit my pack parametre.
Steps:
1 – Click Package
2 - Menu « Action » -> Edit Pack Parametre
3 – A new error page appears
« The page cannot be displayed. The object may have been deleted or you may not have sufficient privileges to see it. » ( see image in attachement file)

Note: I'm connected with an administrator AD Account and I can publish a package and see the portal content in framework manager.
Please, there is any way to resolve this problem?

Thanks!
