Woocommerce doesn't show reviews/comments on product page. How to fix?

Question

WordPress

Here is the code that displays the comments.

<?
global $product;
?>
<div id="reviews" class="woocommerce-Reviews">
    <div id="comments">
      <h2 class="woocommerce-Reviews-title">
            <?php
            $count = $product->get_review_count();
            if ( $count && wc_review_ratings_enabled() ) {
                /* translators: 1: reviews count 2: product name */
                $reviews_title = sprintf( esc_html( _n( '%1$s review for %2$s', '%1$s reviews for %2$s', $count, 'woocommerce' ) ), esc_html( $count ), '<span>' . get_the_title() . '</span>' );
                echo apply_filters( 'woocommerce_reviews_title', $reviews_title, $count, $product ); // WPCS: XSS ok.
            } else {
                esc_html_e( 'Reviews', 'woocommerce' );
            }
            ?>
        </h2> 

        <?php if ( !have_comments() ) : ?>
            <ol class="commentlist">

            </ol>

            <?php

    <div class="clear"></div>
</div>

But this is how it displays it on the page.


On the product editing page, everything is fine.


As you can see in the code, the if ( !have_comments() ) check has an exclamation mark. I put it, because for some reason it returns false, although it should be true.

Also, for your convenience, here's another.
How it looks on my site.


How it should look.

Answer 1

I found a solution here - https://web-answers.ru/php/rating-woocommerce-ne-...
(Answer that is highlighted in green, step 2).
Duplicate here:
If the reviews are still not showing up, copy your theme's "page.php" as "woocommerce.php". Delete loop -

<?php if(have_posts()): while(have_posts()): the_post(); ?> а также <?php endwhile; endif; ?>

, replace the_content() с woocommerce_content(),
To be honest, I did not have some points, as he described, what I did:
Removed get_template_part( 'template-parts/content', 'page' );
replaced the_post() with woocommerce_content()
Removed while(have_posts() ): and, accordingly, endwhile
After that, it worked, but it looked bad, there were no styles. It can be seen really, the topic does not support, for this campaign you will have to draw it up yourself.
