First, thanks for the plugin, it is amazing.
My problem is in applying function related_posts().
Doing this, I have a list with 4 posts:
1 - these 4 posts do not appear to be related to the current post.
2 ° all pages display the same 4 posts.
Interesting fact: When we do not apply the related_posts () function those that appear below the content is related to the current post. So everything works fine. Strange.
Do you know what I've done wrong?
