Если я добавлю шорткод без WP Bakery и через сделать шорткод на странице, но результат будет таким же

I created my own shortcode to display popular news for the day, week, month and year, data from the Post view Counter plugin. When outputting the shortcode, nothing is output, and all the collected on the main page disappear and in its place becomes an empty output of news. In my shortcode, I added my own css and js, adding them to function.php and activating them in the template settings as a shortcode. Here is an example of my php code: 

<div id="tab1" class="tab active"><?php
$today_start = date('Y-m-d 00:00:00');
$today_end = date('Y-m-d 23:59:59');

$popular_posts = pvc_get_most_viewed_posts(array(
    'posts_per_page' => 4,
    'orderby' => 'views',
    'order' => 'DESC',
  'start' => $today_start,
  'end' => $today_end,
    'date_query' => array(
        'after' => $today_start,
        'before' => $today_end,
        'inclusive' => true,
    ),
));

foreach ($popular_posts as $post) {
    setup_postdata($post);
?>
    <div class="gallery-item">
        <?php if (has_post_thumbnail()) { ?>
            <div style="background-image: url(<?php esc_url(the_post_thumbnail_url('full')); ?>);">
                <?php the_post_thumbnail('gallery-item', array('class' => 'custom-thumbnail-class')); ?>
            </div>
        <?php } ?>
        <span class="caption">
            <h2><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
            <?php echo get_the_date('F j, Y'); ?>
        </span>
    </div>
<?php
}
wp_reset_postdata();
?>
    </div>
