When testing payments with PayPal if the user hits "Cancel and Return to 'Merchant Name'" the return URL looks like:

/Shop/Payment/orderid/103/status/0

but the page is blank and the user is not informed that the order has not been paid for . . .the page loads fine, but there is no content or message.

Suggest adding methods for better handling of "Cancel and Return to Merchant" link from PayPal

When playing with the URL if I change it to:
/Shop/Payment/orderid/103/status/30
the order appears to complete with the page content of:

====== PAGE CONTENT ==========

Hi
please can somebody give me a hint what the following error may be caused by?

I am using Openstore version 4.1.5 on DNN 9.3.2 and followed the instructions in the integrator manual and various hints I found via google-search.

I configured anything as I remembered how to do it but the "old" documentation from nb-Store seems no more available - The paypal integration was described in more detail there than in the current documentation - as far as I remember.

I am seeing this Error in the BackOffice/Admin/OS_Paypal Payment Plugin Settings on the very bottom of the page...
OS_PayPal ERROR: System.FormatException: Input string was not in a correct format. at System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal) at System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info) at System.Convert.ToInt32(String value) at OS_PayPal.PayPalIpnParameters..ctor(HttpRequest ipnRequest) at OS_PayPal.DNN.NBrightStore.OSPayPalNotify.ProcessRequest(HttpContext context)

The transactions payd with paypal work and I am returned to the payment_Ok template/page
But the Orders-Area in BackOffice always shows "Payment not verified" instead of "payment OK"

Thanks in advance and kind regards
Gerald
