Proposed changes to MAE – Related Post

MAE – Related Post only renders posts that have the same first tag as the current post. This does not always work as many people only use post categories. I would suggest extending it so it works with both tags and categories.

if ( has_tag() ) {
                $tags = wp_get_post_tags( get_the_ID() );

                $args = array(
                    'post_type' => 'post',
                    'tag__in' => $tags,
                    'post__not_in' => array( get_the_ID() ),
                    'posts_per_page' => -1
                );
            } else {
                $cats = wp_get_post_categories( get_the_ID() );
                $args = array(
                    'post_type' => 'post',
                    'category__in' => $cats,
                    'post__not_in' => array( get_the_ID() ),
                    'posts_per_page' => $settings['posts_per_page']
                );
            }
