in the checkout.php at line 730 there is a bug. The shipping/ billing address is wrong.
<div style="margin-bottom:2px"><b><?=word_lang("address")?></b></div>
<div style="margin-bottom:10px"><input class="ibox" name="billing_address" value="<?=$_SESSION["billing_address"]?>" style="width:200px"></div>
Change please to in the next update:
<div style="margin-bottom:2px"><b><?=word_lang("address")?></b></div>
<div style="margin-bottom:10px"><input class="ibox" name="shipping_address" value="<?=$_SESSION["shipping_address"]?>" style="width:200px"></div>
Thx
