Order status error

[mixix]

This is now a repost. I NEED some/any input! Client is waiting and Prestashop is screwing around -

 

When updating an order status, I'm getting the following error:

 

"Fatal error: Call to undefined method ShopUrl::cacheMainDomainForShop() in /public_html/classes/order/OrderHistory.php on line 91"

 

This is a fairly fresh installation of Prestashop 1.5.6 with a single theme, no outside modules have been used or installed.

 

Any ideas what's causing it and a plausible approach to fixing it which doesn't involve wiping everything and starting fresh? For example, what is the location and purpose of the function being called? What consequences would it have if the lines was removed?

How did you install presta? Open that class (shopUrl) and look for this

	public static function cacheMainDomainForShop($id_shop)
	{
		if (!isset(self::$main_domain_ssl[(int)$id_shop]) || !isset(self::$main_domain[(int)$id_shop]))
		{
			$row = Db::getInstance()->getRow('
			SELECT domain, domain_ssl
			FROM '._DB_PREFIX_.'shop_url
			WHERE main = 1
			AND id_shop = '.($id_shop !== null ? (int)$id_shop : Context::getContext()->shop->id));
			self::$main_domain[(int)$id_shop] = $row['domain'];
			self::$main_domain_ssl[(int)$id_shop] = $row['domain_ssl'];
		}
	}

If not present, add it

Yes, thank you! That and one more function was missing in the class. No idea why. I used a 1-click installation provided by webhost.
