I've been following this tutorial https://blog.pythonanywhere.com/35/ on
creating a Facebook Canvas app using PythonAnywhere's Django web app.
When creating a Django web app, I was asked to choose the Python
version. I was able to finish the tutorial and it seems to be working
for Python 2 without any problems, however it's no longer supported so I
decided to upgrade to Python 3.4 and deleted the old app. I'm using the
django_facebook
and installed it with pip3.4 install --user
on
.local
directory as recommended by PythonAnywhere and went thru the
tutorial again, but when I check the Facebook app, the canvas doesn't
appear. This is what I find in the PythonAnywhere Error Log:

It says django_facebook.auth_backends.FacebookBackend wasn't found, but it's there in my settings.py:

I've done a web search on this, but it seems like I'm the only who's having this issue. I'm early to Django and web programming in general and I really want to find out what's causing this error and if there's a fix to it.
The installation instructions mention that it's necessary to add a
AUTH_USER_MODEL
setting and I don't see that in yoursettings.py
. You may have missed other steps, but I haven't checked fully.
