Rails 3.2 + Facebook auth + CSRF FAILURE
===

Could not authorize you from Facebook because "Csrf detected".

This is the error that I see when trying to login via facebook, I always see that error. Can't seem to get rid of it. I put a skip 


  skip_before_filter :verify_authenticity_token

on the Omniauth callback, but still I get the error. This is in both local and prod (heroku) environments. I have set the heroku environment variables. Any idea?
