That exception is mentioned in the Django troubleshooting docs have a look at that.

Still don't get it. Can you have a look at my code?

Nothing jumps out at me. Try removing stuff (comment out some of your installed apps, comment out bits of models etc.) to narrow it down.

I have tried commenting out things as suggested, and even downgraded from Django 1.7 to 1.5 in vain.

Hang on, "AppRegistryNotReady" error doesn't exist in django 1.5 as far as I know -- are you definitely still seeing the same problem?

I have pip uninstall django inside my virtualenv and reinstall Django 1.5. It still didn't work. I've looked everywhere and got no clue where the code breaks, and it worked just fine locally. So, one thing I suspect is that in the settings.py I'm still using Postgresql. Although unlikely, can that be the source of this problem?

Can you check your django version inside /home/CheshireCat/.virtualenvs/perfectus/lib/python2.7/site-packages/django/__init__.py?

Now I've changed to PythonAnywhere's default version:

VERSION = (1, 6, 5, 'final', 0)

and hey, now the traceback changed

Aha!

And now that error does sound like it might be to do with an incompatible settings.py... Can you copy-over a settings.py generated with 1.6.5, and just put your database settings, etc, back?

Harry, I finally got my site on!

Shouldn't have play around with the dev fire. Though it's a shame to ditch the migration feature of 1.7. (I actually learned about that feature from your book

hooray!

definitely a shame re: 1.7, but I guess sometimes you run out of time for debugging...
