My address_book.php file has the below on line 76
Code:
} elseif ($current_area != 'C') {
after the closing tag on line 87 I just added
Code:
elseif ($current_area == 'C' && !empty($address_book)) {
$address_book = func_customer_save_address_book_indb($address_book, @$ship2diff, @$existing_address, @$new_address);
}
