Problem importing comments

Hi all,

I recently imported my blog: https://www.wysinnwyg.com/blog and I’m having problem with the comments. Most of the comments have disappeared, and the ones that haven’t are appearing on the wrong posts.

On top of the post, right below the post title, the site correctly displays the number of posts that I had before I imported the comments by this function call in single.php:

<?php comments_number('no responses','one response','% responses'); ?>

However, this function call in comments.php:

<?php comments_number('No Comments', '1 Comment', '% Comments'); ?>

returns the number of the comments that are ACTUALLY on the page (which is different from the first number because not all the comments are appearing, and not in the right place).

What do I do?

P.S. this is the full comments.php:

Thanks!
