Спасибо.

А в engine/modules/functions.php ничего переделывать не нужно?
И на что это повлияет если в engine.php переделать, а в functions.php так оставить?

function get_breadcrumbcategories($id) {
	
	global $cat_info, $config, $PHP_SELF;
	
	if( ! $id ) return;
	
	$parent_id = $cat_info[$id]['parentid'];
	
	if( $config['allow_alt_url'] ) $list = "<span itemscope itemtype=\"http://data-vocabulary.org/Breadcrumb\"><a href=\"" . $config['http_home_url'] . get_url( $id ) . "/\" itemprop=\"url\"><span itemprop=\"title\">{$cat_info[$id]['name']}</span></a></span>";
	else $list = "<span itemscope itemtype=\"http://data-vocabulary.org/Breadcrumb\"><a href=\"$PHP_SELF?do=cat&amp;category={$cat_info[$id]['alt_name']}\" itemprop=\"url\"><span itemprop=\"title\">{$cat_info[$id]['name']}</span></a></span>";
	
	while ( $parent_id ) {
		
		if( $config['allow_alt_url'] ) $list = "<span itemscope itemtype=\"http://data-vocabulary.org/Breadcrumb\"><a href=\"" . $config['http_home_url'] . get_url( $parent_id ) . "/\" itemprop=\"url\"><span itemprop=\"title\">{$cat_info[$parent_id]['name']}</span></a></span>" . " &raquo; " . $list;
		else $list = "<span itemscope itemtype=\"http://data-vocabulary.org/Breadcrumb\"><a href=\"$PHP_SELF?do=cat&amp;category={$cat_info[$parent_id]['alt_name']}\" itemprop=\"url\"><span itemprop=\"title\">{$cat_info[$parent_id]['name']}</span></a></span>" . " &raquo; " . $list;
		
		$parent_id = $cat_info[$parent_id]['parentid'];
		
		if( $cat_info[$parent_id]['parentid'] == $cat_info[$parent_id]['id'] ) break;
	
	}
	
	return $list;
}
