Hi,
In the file "components/com_hikashop/views/checkout/tmpl/address_selector.php" please replace
url = '<?php echo hikashop_completeLink('address&task=edit&cid=0&type={TYPE}&fid=hikashop_checkout_{TYPE}_address_zone', true, true); ?>'.replace(/\{TYPE\}/g, type);
By
url = '<?php echo hikashop_completeLink('address&task=edit&cid=0&address_type={TYPE}&fid=hikashop_checkout_{TYPE}_address_zone', true, true); ?>'.replace(/\{TYPE\}/g, type);
And also
var url = '<?php echo hikashop_completeLink('address&task=show&cid={CID}&type={TYPE}&fid=hikashop_checkout_{TYPE}_address_zone', true, true); ?>'.replace(/\{CID\}/g, el.value).replace(/\{TYPE\}/g, type);
By:
var url = '<?php echo hikashop_completeLink('address&task=show&cid={CID}&address_type={TYPE}&fid=hikashop_checkout_{TYPE}_address_zone', true, true); ?>'.replace(/\{CID\}/g, el.value).replace(/\{TYPE\}/g, type);
We will update the HikaShop package with the patch as soon as possible.
Regards,
