Hi, I am having the same problem. I have a new install of zencart 1.3.9h with stock by attribute addon. I am using authorizenet and paypal standard IPN. I received an order from a customer thru paypal but it was an echeck.
I did not receive anything from zencart to notify me of the sale and there is nothing in admin to show the sale. I received a paypal notification that I received an echeck and that is how I found out about the sale. i had to get in touch with the customer to find out about the sale details. Can any one help me please?
Authorizenet and regular payapl transactions are fine, it is only paypal echecks that are an issue for me.
