I have been struggling with a fresh installation of this... Everything seems to work fine but when i try to access the 'User Permissions' or 'Group Permissions' with my admin account i got:
Sorry, a session error has occurred
It is possible that your session has expired or your login credentials do not allow access to this resource. See error text below for further details:
SESSION ERROR: '__DEFAULT__': internet/defer:151,admin/auserperm:1528,admin/auserperm:1488,admin/auserperm:1009 (exceptions.KeyError)
Any ideas? Thank you all,
