Rails 3.1.0 - undefined method `page_cache_extension' for ActionController::Base:Class

Question

When I try load my rails 3.1 app I just get this error. Any ideas?

undefined method 'page_cache_extension' for ActionController::Base:Class

Answer 1

I removed the following lines from development.rb

config.action_view.debug_rjs             = true
config.action_controller.perform_caching = false

Not sure if this is right, but it worked for me.

Answer 2

somewhere I've read that it could be caused because of empty database - do You have one? Check if there You have any records ;) This resolved my problem with it.
