Hello zwaarcontrast,
Than you for your reply.
I tried similar code and worked.
I think the problem is when I check if the field ‘‘file’ is not empty to not show it in this case.
$link = get_sub_field(‘file’);
$name = get_sub_field(‘file_name’);
?>
<?php if( $link ): ?>
<a href=”<?php echo $link; ?>” target=”_blank”> <?php echo $name; ?>
<?php endif; ?>
</a>
Are you sure there are no downloads present?
Yes, I am.
When There is a attached file look like this:

and when there is not files look like this:

It’s strange because I don’t have any error in my error log also the debug of WP and my server is ON so.. I don’t know exactly what is the problem.
Thank you!
