Hi,
That's indeed the case.
The current version of the plugin is not sending the address to PayPal Advanced.
Try to change the code:
"&BILLTOFIRSTNAME=".$order->cart->billing_address->address_firstname.
"&BILLTOLASTNAME=".$order->cart->billing_address->address_lastname;
to:
"&BILLTOFIRSTNAME=".@$order->cart->billing_address->address_firstname.
"&BILLTOLASTNAME=".@$order->cart->billing_address->address_lastname.
"&BILLTOSTREET=".@$order->cart->billing_address->address_street.
"&BILLTOCITY=".@$order->cart->billing_address->address_city.
"&BILLTOZIP=".@$order->cart->billing_address->address_post_code.
"&BILLTOSTATE=".@$order->cart->billing_address->address_state->zone_name.
"&BILLTOCOUNTRY=".@ $order->cart->billing_address->address_country->zone_code_2.
"&SHIPTOFIRSTNAME=".@$order->cart->shipping_address->address_firstname.
"&SHIPTOLASTNAME=".@$order->cart->shipping_address->address_lastname.
"&SHIPTOSTREET=".@$order->cart->shipping_address->address_street.
"&SHIPTOCITY=".@$order->cart->shipping_address->address_city.
"&SHIPTOZIP=".@$order->cart->shipping_address->address_post_code.
"&SHIPTOSTATE=".@$order->cart->shipping_address->address_state->zone_name.
"&SHIPTOCOUNTRY=".@ $order->cart->shipping_address->address_country->zone_code_2;
in the file plugins/hikashoppayment/paypaladvanced/paypaladvanced.php and that should help.
