Devise, OmniAuth & Facebook: “Not found. Authentication passthru.”

Question

Trying to follow along with https://github.com/plataformatec/devise/wiki/OmniAuth:-Overview and I\'m stumped.

I\'ve got config.omniauth :facebook, ENV[\'FB_AP

Answer 1

I had the same error.
What worked for me was restarting the rails server, to reflect the changes (config.omniauth :facebook, ENV['FB_APP_ID'], ENV['FB_APP_SECRET']) I had made to config/initializers/devise.rb.
