When trying to access localhost:3000/static_pages/home I get the following error:

SyntaxError in StaticPagesController#home

You’re application_helper.rb seems to be broken. You probably want something like this:

module ApplicationHelper

  def full_title(page_title)
    base_title = "Ruby on Rails Tutorial Sample App"
    if page_title.empty?
      base_title
    else
      "#{base_title} | #{page_title}"
    end
  end

end

Seems the module line got missing. That’s why Ruby is complaining about an additional end in the last line.
