Hi,

I just tried to upgrade, but now I have some issues:

- I had 4.0.0 working -Then I downloaded 4.1.1 and do config and make - I pip installed django-hstore - then service nav stop, make install - service nav start

Now It complains that ipdevpoll failed to start and I'm also unable to log in to web interface with 500 Error. I can see this error in apache error log:

[Tue Sep 23 14:04:33 2014] [error]] mod_wsgi (pid=16795): Exception occurred processing WSGI script '/usr/local/nav/lib/python/nav/wsgi.py'. [Tue Sep 23 14:04:33 2014] [error] Traceback (most recent call last): [Tue Sep 23 14:04:33 2014] [error]] File "/usr/local/lib/python2.7/dist-packages/django/core/handlers/wsgi.py", line 219, in __call__ [Tue Sep 23 14:04:33 2014] [error] self.load_middleware() [Tue Sep 23 14:04:33 2014] [error] File "/usr/local/lib/python2.7/dist-packages/django/core/handlers/base.py", line 47, in load_middleware [Tue Sep 23 14:04:33 2014] [error] raise exceptions.ImproperlyConfigured('Error importing middleware %s: "%s"' % (mw_module, e)) [Tue Sep 23 14:04:33 2014] [error] ImproperlyConfigured: Error importing middleware nav.django.auth: "cannot import name force_str"

I suppose, that I missed some steps in the upgrade process.

Can you please suggest, what can be done?
