Most liked page not displaying posts

Thats code just querying the posts by sorting it by meta value, but you have no loop for the posts to display. Add the loop after the query for something like this:

echo '<ul>';
if ( have_posts() ) : while ( have_posts() ) : the_post();
    echo '<li>';
    the_title();
    echo '</li>';
endwhile;
endif;
echo '</ul>';
