Maybe could you paste the full code.

Maybe could you replace your code
<?php
$get_cats = wp_list_categories( 'orderby=name&echo=0&depth=1&show_count=1&title_li=' );
$cat_array = explode('</li>',$get_cats);
$results_total = count($cat_array);
$cats_per_list = ceil($results_total / 4);
$list_number = 1;
$result_number = 0;
?>
<div class="cat-col-<?php echo $list_number; ?>">
<?php
foreach($cat_array as $category) {
$result_number++;
if($result_number % $cats_per_list == 0) {
$list_number++;
echo $category.'</li>
</div>
<div class="cat-col-'.$list_number.'">';
}

Bob answers:

Here is function that might help.
let me know if this function give you related posts.
if it works then we need to add only css to manage it.


function show_related_posts($title = 'Related Posts', $count = 3) {

global $post;

$tag_ids = array();

$current_cat = get_the_category($post->ID);
$current_cat = $current_cat[0]->cat_ID;
$this_cat = '';

$tags = get_the_tags($post->ID);

if ( $tags ) {
foreach($tags as $tag) {
$tag_ids[] = $tag->term_id;
}
} else {
$this_cat = $current_cat;
}

$args = array(
'post_type' => get_post_type(),
'numberposts' => $count,
'orderby' => 'rand',
'tag__in' => $tag_ids,
'cat' => $this_cat,
'exclude' => $post->ID
);

$related_posts = get_posts($args);

/**
* If the tags are only assigned to this post try getting
* the posts again without the tag__in arg and set the cat
* arg to this category.
*/
if ( empty($related_posts) ) {
$args['tag__in'] = '';
$args['cat'] = $current_cat;
$related_posts = get_posts($args);
}

if ( empty($related_posts) ) {
return;
}

$post_list = '';

foreach($related_posts as $related) {
$img = "";

if(has_post_thumbnail( $related->ID ))
$img = get_the_post_thumbnail($related->ID, 'thumbnail');

$post_list .= '<li><a href="' . get_permalink($related->ID) . '">' . $img .'<br />'. $related->post_title . '</a></li>';
}

return sprintf('
<div class="related-posts">
<h4>%s</h4>
<ul>%s</ul>
</div> <!-- .related-posts -->
', $title, $post_list );
}


You need to add <strong>show_related_posts();</strong> in single.php
