Gift Certificate setup

[mikajlo]

I have tried to setup a Gift Certificate product as described in FAQ section but I have problem to order GC.
At the last step, when I confirm the order I got this error message from the server:

Warning: Invalid argument supplied for foreach() in /hsphere/local/home/mivanovi/mom4kids.nl/includes/classes/order.php on line 750

Warning: Cannot modify header information - headers already sent by (output started at /hsphere/local/home/mivanovi/mom4kids.nl/includes/classes/order.php:750) in /hsphere/local/home/mivanovi/mom4kids.nl/includes/functions/functions_general.php on line 41

Anybody knows how this can be fixed?

Thanks.

well, it looks like orders.php line 750 causes the problem.

This order.php comes from "Stock By Attribute" mod, so I guess it might be a bug.
