Some of you regulars may have noticed that comments were magically not appearing at the bottom of some of the posts on this blog. I snooped around in the code behind the theme and discovered one line of PHP that caused comments to sometimes show and sometimes not show. I'd like to share what I found to help others who are having the same problem. Let me add this little tidbit: I LOVE this Notepad theme by Nick La (http://ndesign-studio.com/wp-themes). His work is Very excellent. I contacted Nick through his contact form to let him know about the one-line fix to the comments.php file in his theme. I had installed this theme when my blog was running as WordPress 2-something, not 3.
Here is the easy fix: Edit your comments.php file and find this line (roughly line 24):
wp_list_comments('type=comment&callback=mytheme_comment');
Change it to this:
wp_list_comments(array('callback'=>'mytheme_comment'));
Update the file (save it). That should solve the issue.
