Same comments on all posts

Question

I am working on a self-made theme and I have an issue where all of the comments are showing up on all the posts, instead of each post only showing their own comments.

I am using this code to display comments:

<?php if (have_posts()): ?>
  <?php while (have_posts()): ?>
    <?php the_post(); ?>
    // The title, content and some other html here
    wp_list_comments(array( 'callback' => 'comments_callback'), get_comments());
  <?php endwhile; ?>
<?php endif; ?>

And I have tried to both put this line inside and outside the loop, and still get the same result. I got com comments_callback funktion in a mu-plugins and the code for it looks like this:

<?php
function comments_callback( $comment, $args, $depth ) {
    $GLOBALS['comment'] = $comment;
    ?>
    <div class="the-comment">
      <div class="blog-comment-avatar">
        <i class="fa fa-user" aria-hidden="true"></i>
      </div>
      <div class="comment-text">
      <p class="text-secondary comment-author"><?php comment_author(); ?></p>
        <?php comment_text(); ?>
      </div>
    </div>
    <?php
}
?>

What am I doing wrong here?

I was able to reproduce the issue. It's being caused by the loop in your code:

<?php if (have_posts()): ?>
  <?php while (have_posts()): ?>

Replace that standard loop with if ( have_comments() ) {..., like this:

<?php if ( have_comments() ) { ?>
    // The title, content and some other html here
    wp_list_comments(array( 'callback' => 'comments_callback'), get_comments());
<?php endif; ?>
