After the customer has did his purchase

Hi,

That's a bug introduced with the latest version.
Please change the code:
$query='SELECT a.* FROM '.hikashop::table('cart').' AS a WHERE '.$filter.' ORDER BY a.cart_modified DESC LIMIT 1';
$this->database->setQuery($query);
$this->cart = $this->database->loadObject();
to:
if(!empty($filter)){
$query='SELECT a.* FROM '.hikashop::table('cart').' AS a WHERE '.$filter.' ORDER BY a.cart_modified DESC LIMIT 1';
$this->database->setQuery($query);
$this->cart = $this->database->loadObject();
}else{
$this->cart = null;
}

in the file administrator/components/com_hikashop/classes/cart.php and try again. That should solve the problem.

Mmm. That should have worked. Could you double check the modification ?

If that doesn't work, please also change the line:
$filter = implode(' OR ',$this->filters);
to:
if(!empty($this->filters)){
$filter = implode(' OR ',$this->filters);
}
and try again.

Yes please. You can send the access via our contact form: www.hikashop.com/en/support/contact-us.html
please specify the url of that thread so that we know why you're sending your accesses.

I looked at your cart.php file and I saw that you didn't do the first modification I talked about. I've done it. Could you tell us if it works now ?
