Popular posts

Hi everyone,

I am trying to display the most popular posts on Blog page, but nothing works. I’ve tried several codes and can’t manage.

For example:

<?php
								$args=array(
									'meta_key' => 'post_views_count',
									'orderby' => 'meta_value_num',
									'posts_per_page' => 2
						      	);

				      			$my_query = null;
								$my_query = new WP_Query($args);
								if( $my_query->have_posts() ) {
									while ($my_query->have_posts()) : $my_query->the_post(); ?>
										<div class="col-sm-12">
											<?php get_template_part('template/blog-summary'); ?>
										</div>
										<?php
									the_content();
									endwhile;
								}
							?>

or https://digwp.com/2016/03/diy-popular-posts/.

But it does not display a thing, why is that?

Thank you!
