Error returning from PayPal standard

Hi all,

I'm using DNN 5.5.1 and Smith Cart 4.2.1.

A customer made a successful PayPal purchase, but had an error when they returned from PayPal to the confirmation screen. We received confirmation from PayPal, but none from Smith Cart. This is doesn't look good and requires reassurance from us to the customer who loses confidence. It seems like an email error.

We also had an order via Eway an hour earlier with troubles at all.

Please advise what went wrong. Here is the exception from the event viewer:

Re: Error returning from PayPal standard

Hi Daniel,

The current version of the cart is 4.31 we don’t maintain source code for versions of the cart more than 3 versions back so we are not able to test the cart to replicate the issue you reported.

Please see the following forum post about configuring the Paypal Standard Return URL:
http://www.smith-consulting.com/Forums/forumid/1/postid/10/scope/posts.aspx

To confirm the issue is fixed in the latest version of the cart you can download the trial version and then upgrade to the latest build to fix the issue.
OR
You can login to our test portal and configure the cart settings to match your cart settings and try to replicate the issue.

Please send an email to kevin@smith-consulting.com if you need a login.

Thanks, Kevin
