Web.py session data disappears during production

First of all, the means of production works with web.config.debug = False

. So the suggested hook from the documentation doesn't help (also tested). This way my Login Script keeps three variables in the session. When I access them within a set function, they return the expected value.

                print session.get("privilege") # Return 0
                print logged() # Return 0
                session.login = 1
                session.privilege = ident['privilege']
                session.userid = ident['id']
                render = create_render(session.get('privilege'))
                print session.get("privilege") # Returns 1 <- as exprected
                print logged() # Returns True as expected
                raise web.seeother('/next')

      

        
        
        
      

    

In the next class, all values ​​are set back to 0. Any ideas? I'm using git and even going back to a previous (working) version didn't help. This behavior suddenly appeared. Only a change I remember doing on the system (OSX Mavericks) sets cliclick.
