First time installation - cannot log in

[Alex Mears]

I've spent many hours myself trying to solve this problem and cannot work out if it's a Mezzanine or Django issue.

I suspect it's a stupid mistake I'm making and would appreciate any help to resolve.

From http://127.0.0.1:8000/admin/login/?next=/admin/

I input my username and password, click 'Log in' and get a Traceback:

You've somehow installed the latest release of Django (1.11) which isn't yet supported by the latest Mezzanine release. The development version of Mezzanine does however support it. 

You can either install Mezzanine as per the documentation, which should install the latest supported release of Django (1.10), or if the latest version of Django is a requirement for you, use development version of Mezzanine by installing it from git.

Thank you so much, Stephen.

I installed the development version of Mezzanine from GitHub and it worked!

I didn't find any mention of Mezzanine only supporting Django (1.10) in the documentation. How did you know?
