Hi Raphael, thanks for writing this up! I made it all the way to the end but when I click any of the links on the page the number doesn't increment and I get the following message on the server. However when I reload the page the number does appear to be incremented.

Hi Tom,

Thank you for reading through the article, and providing me with this feedback. I have update the article with the answer to your question. I also included the answer below for easier reference

In step 7.5, copy-paste this snippet instead. This adds the line redirect_to root_path in the controller function increment_async so it goes to the homepage once the link is pressed.

class HomeController < ApplicationController
  def index
    @message = "Dynamic"

    @posts = Post.all
  end

  def increment_async
    ::IncrementCountWorker.perform_async(params[:post_id])

    redirect_to root_path # THIS IS THE ADDED LINE
  end
end

Excellent, thanks Raphael!
