Your site does not load completely. Whatever I have observed, it seems that you have modified the shortcode functionality. Because with the above shortcode, it will show the result in a tabular manner not the way you have shown. Can you please confirm this? I would like to know the customization (if any) you have made.
There is also a template file
most-liked-posts.php inside the
plugin folder/templates. It has the logic to sort the posts as per like count. Can you please check that as well? That template layout is different from yours so you will have to modify the layout.
