Hi

I made a custom post type with ACF fields: Media, Gallery.

'capability_type' => 'artiste',
'map_meta_cap' => true,
'capabilities' => array(
	// meta caps (don't assign these to roles)
	'edit_post' => 'edit_artiste',
	'read_post' => 'read_artiste',
	'delete_post' => 'delete_artiste',

	// primitive/meta caps
	'create_posts' => 'create_artistes',

	// primitive caps used outside of map_meta_cap()
	'edit_posts'  => 'edit_artistes',
	'edit_others_posts'  => 'manage_artistes',
	'publish_posts' => 'publish_artistes',
	'read_private_posts' => 'read',

	// primitive caps used inside of map_meta_cap()
	'read' => 'read',
	'delete_posts' => 'delete_artistes',
	'delete_private_posts' => 'delete_private_artistes',
	'delete_published_posts' => 'delete_published_artistes',
	'delete_others_posts' => 'manage_artistes',
	'edit_private_posts' => 'edit_artistes',
	'edit_published_posts' => 'edit_artistes'
)

On this post type, I create a custom role.

function manage_artiste_capabilities() {
	$admin = get_role('administrator');
	$galerie = get_role('galerie');
	$caps = array(
		'create_artistes',
		'edit_artistes',
		'publish_artistes',
		'delete_artistes',
		'delete_published_artistes',
		'manage_artistes',
	);

	foreach($caps as $cap) {
		$admin->add_cap($cap);
	}

	$admin->remove_cap('special_galerie');

	// basique
	$galerie->add_cap('upload_files');

	// artistes
	$galerie->add_cap('create_artistes');
	$galerie->add_cap('edit_artistes');
	$galerie->add_cap('publish_artistes');
	$galerie->add_cap('delete_artistes');

}

The admin can add some meta for normal field ou custom (with ACF). The meta are saved and updated
For the custom role, he can add some meta (normal media fields or custom with ACF) but the saved or update method failed.

I made a test for an other post type, on the same website. This one use the normal Editor with built in media. In this case, everything works fine.

Have you an idea? Thanks

That’s a WordPress feature which make the “bug”.
With custom roles, the users can’t edit media. You need to add cap for this role.
This tutorial by Simon Wheatley explain the process.
