Sometime after WordPress 2.7 and before WordPress 2.9.2, I lost a key functionality within WordPress. It’s threaded comments. I blame myself for constantly tinkering around with the theme. I must have deleted a key piece of code somewhere in the theme that prevented threaded comments from working.
For those not familiar with WordPress, the threaded comments functionality allows the “comment form” to jump underneath a specific comment when a “Reply” link is clicked. Clicking “Cancel Reply” restores the “comment form” to its original position. When a comment is submitted, the comment is placed directly underneath that specific comment.
<?php if ( is_singular() ) wp_enqueue_script( ‘comment-reply’ ); ?>
