Hi folks, I am trying to add FB authentication to my site, I got it to work locally, but I keep getting this error every time I push to heroku. I'm not sure how/what to fix it, I guess it's coming from this section. I tried to replace "app_domain" with my domain and it didn't work. Any ideas? Thanks in advance for any help! I used this tutorial for Devise/Omniauth: http://sourcey.com/rails-4-omniauth-using-devise-with-twitter-facebook-and-linkedin/ # Email config.action_mailer.delivery_method = :smtp config.action_mailer.perform_deliveries = true config.action_mailer.default_url_options = { :host => config.app_domain } config.action_mailer.smtp_settings = { address: 'smtp.gmail.com', port: '587', enable_starttls_auto: true, user_name: 'someuser', password: 'somepass', authentication => :plain, domain => 'somedomain.com' } Below is the error:
