So, I've been doing lots of searches and reading and I still can't figure out how to use the Related Posts plugin.
The database is setup, I checked with phpmyadmin and all the fields were created. Now, what do I have to do next? Do I have to enter this code <?php related_posts(); ?> in the posts that I write? I did that, and I one theme, nothing was displayed and in the 2nd one, the related posts were listed at the top of the post, and on the bottom right before comments, it was just a header "Related Posts" and nothing else. This was with a K2 theme and the first one was the Glued Subtle theme.
Am I missing something? What am I doing wrong?
