Resolve for relateded post 🙂 juste add ‘post_type’ => array(‘memes’, ‘post’,’artwork’),

/*  Related posts
/* ------------------------------------ */
if ( ! function_exists( 'hu_related_posts' ) ) {

  function hu_related_posts() {
    wp_reset_postdata();
    global $post;

    // Define shared post arguments
    $args = array(
      'post_type'           => array('memes', 'post','artwork'),
      'no_found_rows'       => true,
      'update_post_meta_cache'  => false,
      'update_post_term_cache'  => false,
      'ignore_sticky_posts'   => 1,
      'orderby'         => 'rand',
      'post__not_in'        => array($post->ID),
      'posts_per_page'      => 3
    );
    // Related by categories
    if ( hu_get_option('related-posts') == 'categories' ) {

      $cats = get_post_meta($post->ID, 'related-cat', true);

      if ( !$cats ) {
        $cats = wp_get_post_categories($post->ID, array('fields'=>'ids'));
        $args['category__in'] = $cats;
      } else {
        $args['cat'] = $cats;
      }
    }
    // Related by tags
    if ( hu_get_option('related-posts') == 'tags' ) {

      $tags = get_post_meta($post->ID, 'related-tag', true);

      if ( !$tags ) {
        $tags = wp_get_post_tags($post->ID, array('fields'=>'ids'));
        $args['tag__in'] = $tags;
      } else {
        $args['tag_slug__in'] = explode(',', $tags);
      }
      if ( !$tags ) { $break = true; }
    }

    $query = !isset($break)?new WP_Query($args):new WP_Query;
