app/controllers/static_pages_controller.rb 

  def home
    if logged_in?
      @micropost  = current_user.microposts.build
      @feed_items = current_user.feed.paginate(page: params[:page])
    end
  end

The user is not signed in. Therefore, the current_user method is returning nil, and ruby can't find the feed method.

You could change the code to this:

@title = "Home"
if signed_in?
    @post = Post.new
    @feed_items = current_user.feed.paginate(:page => params[:page])
end

Now, the new post and the feed items will only be retrieved when the user is signed in.
