Hello Mr. Gilles,
Hope you can find some time to point me in the right direction. I have the following last two problems with the deployment of my store:
1. PayPal Gateway SECURITY ALERT! -
An Instant Payment Notification (IPN) has been received from PayPal containing wrong information. This could be a possible fraud. Please consult your site log for details.
After reading several of your replys I tried - Payment Data Transfer allows you to receive notification of successful payments as they are made. The use of Payment Data Transfer depends on your system configuration and your Return URL. So I anwsered Yes to the switch and put my home return page in. I tried it without the Identity Token that PayPal says to use and got the message. I then tried to find out where to put this token and saw a place under Language Management, Store, Paypal Provider, Resource Name:IPNPOSTString.Text. Thinking this is where it goes I put the PayPal Token there. Still no luck so I put what was there back, "IPN POST String".
2. PayPal's application of taxes is working. But on the return back to my site and order details, the taxes don't show up. I am thinking it is related to this IPN somehow.
All and All store is a nice application and I am not changing. I have to turn taxes of though because of all the pricing communication between the store and customer.
Possible fraud, order not found or order infos are incorrect.
