Rails: Application.html.erb suddently stopped rendering - ruby-on-rails

Question

I was doing something completely different with my app, when suddently my application.html.erb stopped rendering in my views. I even took back all the changes I had made and that did not fix the problem. What can have happened? I've searched everywhere and tried different things, nothing works. Everything else works fine. Here are the files with the changes.
application_controller
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.

#name = attributes[:name]
#email = attributes[:email]
end
def createRound
#gamerounds = Gameround.all
#gameround = Gameround.new({endtime: 'John Appleseed', active: true})
respond_to do |format|
if #gameround.save
format.html { redirect_to #gameround, notice: 'Gameround was successfully created.' }
format.json { render :show, status: :created, location: #gameround }
else
format.html { render :new }
format.json { render json: #gameround.errors, status: :unprocessable_entity }

# Example resource route with concerns:

# # Directs /admin/products/* to Admin::ProductsController
# # (app/controllers/admin/products_controller.rb)

Answer 1

You are defining the initialize method in your controller without calling super.
def initialize(attributes = {})
#name = attributes[:name]
#email = attributes[:email]
super
end
