 * Hey there,
 * I want to change the related articles from currently (same or similiar tags) 
   to new (same category) …
 * I did find a related_posts.php in my theme-editor but don’t really know how to
   change it – I tried several things but nothing really worked …
 * I would really appreciate some help on this! Thank you in advance!!
 * That’s the code:
 *     ```
       <?php
       $theme_settings = korra_theme_settings();
   
       // get current post tags
       $tags_obj = wp_get_post_tags($post->ID);
       if( !$tags_obj ){ return; }
   
       $tags = array();
       foreach( $tags_obj as $term ){
       	$tags[] = $term->term_id;
       }
   
       $tax_query = array(
       	array(
       		'taxonomy' => 'post_format'
       		,'field' => 'slug'
       		,'terms' => array('post-format-link','post-format-aside','post-format-status','post-format-quote')
       		,'operator' => 'NOT IN'
       	)
       );
   
       $args=array(
       	'tag__in' => $tags
       	,'post__not_in' => array($post->ID)
       	,'posts_per_page' => 4
       	,'ignore_sticky_posts' => 1
       	,'orderby' => 'rand'
       	,'meta_key' => '_thumbnail_id' // contain featured image
       	,'tax_query' => $tax_query
       );
   
       $query = new WP_Query($args);
   
       if( $query->have_posts() ):
   
       ?>
   
       <h2 class="description-heading--large">
       	<?php echo esc_html( $theme_settings['post_related_title'] ); ?>
       </h2>
   
       <div class="loop-container loop-container--style-related">
       <?php while ($query->have_posts()) : $query->the_post();
   
       	get_template_part( 'loop_item', 'related' );
   
       endwhile; ?>
   
       </div>
   
       <?php endif; ?>
       <?php wp_reset_postdata(); ?>
       ```

 * You want to get related posts by the same category terms instead of the same 
   tags, correct?
 * Change `wp_get_post_tags($post->ID)` to `wp_get_post_categories($post->ID)`
 * Change `'tag__in' =>` to `'category__in' =>`
 * It’s not required, but all the variables with “tags” in their name is a bit confusing
   for anyone reading the code. It’d be nice if they all were “cats” instead. If
   you do this change, do it carefully, consistently, and fully. I recommend keeping
   a back up copy of the original file in case things go badly. It’s possible I 
   may have missed an important change.
