    How can I change related post by category to related post by tags ?
    This is my code, i get it from related-post.php. I am using Wiles theme

    <?php
/** Latest Posts from the same Category
 * @package wiles **/
global $wiles_option;
$categories = get_the_category( $post->ID );
$first_cat ='';
if(isset($categories[0]->cat_ID)){
$first_cat = $categories[0]->cat_ID;
}
$posts_to_show =  $wiles_option['single_related_posts_to_show'];
$args = array(
	'category__in' => array( $first_cat ),
	'post__not_in' => array( $post->ID ),
	'posts_per_page' => 6,
  'orderby' => 'rand'
);
$related_posts = get_posts( $args );
if( $related_posts ) {
?>
	<section class="single-box related-articles">
        <h4 class="entry-title">
          <?php _e('You May Also Like', 'wiles'); ?>
        </h4>
			<?php foreach( $related_posts as $post ): setup_postdata( $post ); ?>
			<div class="related-article four-col">
                  <figure class="entry-image">
                      <a href="<?php the_permalink(); ?>">
						  <?php
                          if ( has_post_thumbnail() ) {
                              the_post_thumbnail( 'small');
                          } else { ?>
                          <img src="<?php  echo get_template_directory_uri(); ?>/images/default-image.png" alt="<?php the_title();  ?>" />
                          <?php } ?>
                      </a>
                  </figure>
                          <h5><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h5>
              </div>
    		<?php endforeach; ?>
	</section><!-- .single-box .related-posts -->
<?php
} else {
	return;
}
wp_reset_postdata();
?>

    I’ve replaced your loop so that posts become related via the tags they have:

    global $post;
$tags = wp_get_post_tags($post->ID);
if ($tags) {
	$tag_ids = array();
	foreach($tags as $tag) $tag_ids[] = $tag->term_id;
	$args = array('tag__in' => $tag_ids, 'post__not_in' => array($post->ID), 'posts_per_page' => 6, 'orderby' => 'rand');
	$related = new wp_query($args);
	if ($related->have_posts()) { ?>
		<section class="single-box related-articles">
			<h4 class="entry-title"><?php
				_e('You May Also Like', 'wiles'); ?>
			</h4><?php
			while ($related->have_posts()) : $related->the_post(); ?>
				<div class="related-article four-col">
					<figure class="entry-image">
						<a href="<?php the_permalink(); ?>"><?php
							if ( has_post_thumbnail() ) {
								the_post_thumbnail( 'small');
							} else { ?>
								<img src="<?php  echo get_template_directory_uri(); ?>/images/default-image.png" alt="<?php the_title();  ?>" /><?php
							} ?>
						</a>
					</figure>
					<h5><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h5>
				</div><?php
			endwhile; ?>
		</section><?php
	}
}
wp_reset_postdata();

    Let me know how it goes, it should work fine.

    Thank you, but it show : “Parse error: syntax error, unexpected ‘}’ in C:\xampp\htdocs\wp-content\themes\wiles 1.0.4\inc\related-posts.php on line 28”
