I installed Django Sentry following these steps, which works until I start the server and try to log in. If I submit any details (correct or not), I get
ImproperlyConfigured: Module "social_auth.backends.contrib.vkontakte" does not define a "VKontakteBackend" authentication backend
... in the console, the page itself just shows a formatted internal server error.
Is there a way to fix this (preferably without having to change Sentry code)?
