Test items being uploaded to the sidebar
3 comments are uploaded. In chronological order, Louis is the first to post the comment. Wendy is the second and the site dmin is the third. The comment from the site admin is a reply comment for Louis.
Criteria of passing the test
Louis’ comment is located at the top. The site admin’s comment is listed in the second while Wendy’s comment is in the last position.
If a theme has a nested/threaded comment function, you need to enable it in the WP admin.
Setting => Discussions => Other comment settings
Tick “Enable threaded (nested) comments 0 levels deep”
After you have configured the setting and the nested comments does not display, it shows that the theme doesn’t have this function.
