In other words according to my previous post – I have changed the code as you have advised me and it did not solve my issue. New code:

function super_category_toggler() {
	
	$taxonomies = apply_filters('super_category_toggler',array());
	for($x=0;$x<count($taxonomies);$x++)
	{
		$taxonomies[$x] = '#'.$taxonomies[$x].'div .selectit input';
	}
	$selector = implode(',',$taxonomies);
	if($selector == '') $selector = '.selectit input';
	
	echo '
		<script>
		jQuery("'.$selector.'").change(function(){
			var $chk = jQuery(this);
			var ischecked = $chk.is(":checked");
			$chk.parent().parent().siblings().children("label").children("input").each(function(){
var b = this.checked;
ischecked = ischecked || b;
})
			checkParentNodes(ischecked, $chk);
		});
		function checkParentNodes(b, $obj)
		{
			$prt = findParentObj($obj);
			if ($prt.length != 0)
			{
			 $prt[0].checked = b;
			 checkParentNodes(b, $prt);
			}
		}
		function findParentObj($obj)
		{
			return $obj.parent().parent().parent().prev().children("input");
		}
		</script>
		';
	
}
add_action('admin_footer-post.php', 'super_category_toggler');
add_action('admin_footer-post-new.php', 'super_category_toggler');
do_action( 'mvx_add_product_form_end');

I’ve also tried following code, without success aswell:

do_action( 'mvx_add_product_form_end', 'super_category_toggler');

do_action( 'mvx_add_product_form_end.php', 'super_category_toggler');

add_action( 'mvx_add_product_form_end', 'super_category_toggler');

add_action( 'mvx_add_product_form_end.php', 'super_category_toggler');
