I had a customer who made a purchase today and I didn't receive payment. When I go to look at the transaction, it says she paid Paypal, not Paypal IPN like all the others.

When I go to look at her order, on the top is this error message:

Warning: Invalid argument supplied for foreach() in /home/content/......./includes/modules/payment/paypal/paypal_admin_notification.php on line 27

She used a discount coupon & a gift certificate and had a balance left.

Is anyone able to assist me with this or point me in the right direction? I have had my zen cart set up about 9 months now and this is the first time something like this has happened.

Thank you for your time!
