Here is my code and I'm trying to exclude some posts that have been added to the custom post type but it's not working for me, please if anyone can help me??
<div class="grid-x small-up-1 medium-up-3 large-up-3 gridi">
<?php $paged = (get_query_var('paged')) ? get_query_var('paged') : 1; ?>
<?php
$args = array(
'post_type' => 'gallery',
'posts_per_page' => -1,
'post__not_in' => array (779, 1394, 774, 3278),
);
$loop = new WP_Query( $args );
?>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<div class="cell">
<div class="item-navigation">
<a href="<?php the_permalink(); ?>">
<div class="image-container">
<?php the_post_thumbnail(); ?>
<div class="description">
<h5 class="post-title"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h5>
<p><?php the_excerpt(); ?></p>
<a class="read-more" href="<?php the_permalink(); ?>">Read More</a>
</div>
</div>
</a>
</div>
</div>
<?php endwhile; endif; ?>
</div>
