Hello,
1.
As I said, The LG solutions was the name which was added on the XML of the Sofort plugin, but I think that you should contact the user "Boopoo" that you can find through that thread :
www.hikashop.com/forum/payment-methods/8...elopment.html#131701
2.
Regarding your "Must not be empty" errors, you should probably test it by adding through the "sofort.php" file, these lines :
if(isset($order->cart->billing_address))
$Sofort->setSofortlastschriftAddress($order->cart->billing_address->address_firstname, $order->cart->billing_address->address_lastname, $order->cart->billing_address->address_street, '', $order->cart->billing_address->address_post_code, $order->cart->billing_address->address_city, $order->cart->billing_address->address_title, $order->cart->billing_address->address_country->zone_code_2);
just after this line :
$Sofort->setNotificationUrl($notify_url);
3.
Regarding the "Activate this product" error message, you should maybe ask it to Sofort.
