[Facebooker-talk] facebook_session not working for me

[Mike Mangino]

The key is this line:

[#<ActionController::Filters::ClassMethods::SymbolFilter:0x274f3e0
@filter=:ensure_application_is_installed_by_facebook_user>]
rendered_or_redirected.

That means that your Rails app doesn't think the user has the  
application installed. Can you paste in the params that Rails is  
receiving? I would also double check and make sure that you have the  
right API Key and Secret Key in your Facebooker.yml
