The page-not-found error you got is likely a big part of the key to the problem of orders not showing up in your store. We'll need to get more information about what exactly was happening at that stage:
- what was the URL in your browser address bar when that page-not-found appeared?
- in your PayPal logs, there are typically 3 "PayPal_CURL_xxxxxx" files generated with each transaction. Need to see the 3 files from that particular transaction
When you say that the transaction processed correctly anyway, what exactly do you mean by that? Do you mean you got the payment only? or do you mean you also see the order in your Zen Cart admin? Did you get the Zen Cart order-confirmation email?
When these orders aren't showing up in your Zen Cart admin, am I correct that neither you nor the customer are getting order-confirmation emails from the store ... only from PayPal?
