BUG – Attaching taxonomy to Non-Public Post Type not possible

I stand by my setup for having it be just public post types by default, however, I also provided the WP filter so that those who most definitely need the setup could change the parameters to fit their own needs.

function jpburn_non_public_types( $args ) {
    $args['public'] = false;

    return $args
}
add_filter( 'cptui_attach_post_types_to_taxonomy', 'jpburn_non_public_types' );

Will return all of them, regardless of public or not. Add to your functions.php
