I think you are using django-user-accounts , so i think you dont have django-user-accounts installed with pip , or you might have forgot register it to the settings file

INSTALLED_APPS = (
    # ...
    "account",
    # ...
)

and also the template context processor

TEMPLATE_CONTEXT_PROCESSORS = [
    ...
    "account.context_processors.account",
    ...
]

and also middleware

MIDDLEWARE_CLASSES = [
    ...
    "account.middleware.LocaleMiddleware",
    "account.middleware.TimezoneMiddleware",
    ...
]
