Increasing the default number of posts in custom post types

by

I guess ACF is Advanced Custom Fields and CPT custom post type. I’m not used to these acronyms.

Seeing -1 I guess you want to show all of your 26 items.

change numberposts for posts_per_page

<?php 
$args = array(
'posts_per_page' => -1,
'post_type' => 'products', 
'order' =>'ASC',
 );
?>
