I'm getting a "no page found" message when entering comments on a blog I'm working on. I am using a theme called "Piano Forte" that I changed and I didn't realize I broke the comments. So I reinstalled the theme as a separate theme and the comments work on there. So then I compared the index.php, comments-popup.php, and comments.php files and nothing seems out of the ordinary or wrong.
Here is the code from 'index.php' (there is no 'page.php'):
<div id="cats"><p class="postmetadata"><?php the_category(', ') ?> | <?php edit_post_link('Edit','',' | '); ?><?php comments_popup_link('No Comments »', '1 Comment »', '% Comments »'); ?></p><div id="divider"></div></div>
<?php comments_template(); ?>
Any idea what I could have done to create a 404 when editing the 'index.php'? I'm pretty sure that I didn't touch the comments files and it seems that there are no files missing.
