Uninitialized ActionController


#1

Hi, I’m getting this error while in Cloud9 IDE:
/home/ubuntu/rails_projects/alpha-blog/app/controllers/application_controller.rb:1:in `’: uninitialized constant ActionController (NameError)

The application_controller.rb code:
class ApplicationController < ActionController::Base

For APIs, you may want to use :null_session instead.
