Since that class does exist, it sounds like a circular import problem. Now sure how to fix - but I would walk back through the changes you've made from a working version to see where the imports were changed.

Hi,

I don't know the exact problem you are facing, but I have had similar issues in the past due to missing email backend. You may try by configuring a console email backend in your settings.py

EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'

Yeah I have one of those after looking at the settings for the sandbox thought it might be important but made no difference. I have been trying an trying to get this to work I know why I didn't like django again now all I need is a good explanation of how it works with oscar. All I am trying to make is a simple digital download site for stock images I have all the HTML designs and the exact idea I need, just having trouble getting started I did have a developer that was going to build my major functionality but haven't been able to get in touch with them and they haven't got back to me with a price. If the guides and documentation was clearer I could do it myself.

Ben,

I'm guessing you're running Oscar 0.7? I renamed the backend in
https://github.com/tangentlabs/django-oscar/commit/d040fee3f18b46cdc374a780478c2686c2076253

Changing the setting to 'oscar.apps.customer.auth_backends.Emailbackend'
(note the lowercase, non-pythonic B in backend) should do the trick.

My change happened after the release of 0.7. I would've expected the
docs for version 0.7
(http://django-oscar.readthedocs.org/en/releases-0.7/internals/getting_started.html)
to specify the old (correct for <0.8) spelling. I'm sorry about that,
that's a problem with how our docs are build and I will look into that.

Regards,

Maik
