Hello,
I try to upload a web app that runs locally to the web. Locally, the app runs fine.
After uploading it, I tried to access it via the url and I got an error message. The production log is:

I, [2015-06-07T19:52:48.703028 #1110] INFO – : Started GET “/” for 194.219.250.210 at 2015-06-07 19:52:48 +0000

I think I have installed every gem correct. What could be the problem?

Also my review_controller.rb is:

code
```class ReviewController < ApplicationController
  def index
  end

  def new
    @review = Review.new

  end

  def create
    @review = Review.new

    @review.save
    redirect_to @review
  end

  def show
    @review = Review.find(params[:id])
  end

  private
    def review_params
      params.require(:review).permit(:date_of_attendance, :quality_of_speaker, :quality_of_venue, :comment, :first_name, :last_name, :email_address,
:company_name, :company_website)
    end
end

code
