When comments are added to a WordPress post, they are arranged from the oldest to the newest by default. For example, let us look at this WordPress post. We have the oldest comment posted on July 3, 2015, at the top while the newest posted on February 21, 2018, at the time of writing this tutorial appears at the bottom. However, you can reverse this and have the comments showing with the newest at the top and the oldest at the bottom. In this post, I am going to show you how to have the newest comments displaying at the top.
