Answer 1

It looks like your AUTHENTICATION_BACKENDS setting [Django-doc] contains an ellipsis (...). Indeed:

AUTHENTICATION_BACKENDS = (

    # Needed to login by username in Django admin, regardless of `allauth`
    'django.contrib.auth.backends.ModelBackend',

    # `allauth` specific authentication methods, such as login by e-mail
    'allauth.account.auth_backends.AuthenticationBackend',
    ...  # <- an ellipsis
)

You should remove this, so that the AUTHENTICATION_BACKENDS is:

AUTHENTICATION_BACKENDS = (

    # Needed to login by username in Django admin, regardless of `allauth`
    'django.contrib.auth.backends.ModelBackend',

    # `allauth` specific authentication methods, such as login by e-mail
    'allauth.account.auth_backends.AuthenticationBackend'
)

Likely you used a tutorial where the author wanted to say that you can add extra backends, and the elipsis is thus specified for the reader to add more backends, but the Python interpreter of course reads this as an Elipsis object, and the Django system does not understand what you want to say with that.
