Hi:

I've shifted to live testing, but IPN.NET is throwing an error at the postback. Error quoted below.

In connection with the error:

2 identical emails are sent by IPN.NET to the seller re "Payment Error"

2 identical emails are sent by IPN.NET to the customer re "Error Processing Payment"

License Tracker does not see the transaction

PayPal reports by email to me and the customer that the payment was made.

Here is the error from Trace:

Any help would be appreciated.

The error indicates that your host has not allowed permissions for ASP.NET applications running on your server to use access external web URLs (or perhaps just secure URLs ie https). You will need to contact your host to see whether they can fix this.

Hi:

Thanks.

My host suggested that I modify the web.config file to allow full trust--the default is medium.

Still having issues in the sandbox, but the live testing is working.

Thanks again.
