This has already been addressed on this forum but I wanted it to have its own thread.
I'm using 1.3.8a and around the 1st of August about half of the paypal orders never showed up in zencart. The customer paid but an order was never generated. I solved the problem by updating my information in paypal to 'https' instead of 'http'.
Basically, follow the instructions in the zencart Paypal IPN module:
(At some point in the last few zencart versions, these instructions have changed)
Once you have made this change, test it thoroughly.Configuration Instructions:
2. In your PayPal account, under "Profile",
* set your Instant Payment Notification Preferences URL to:
https://www.yoursite.com/ipn_main_handler.php
(If another URL is already used, you may leave it alone.)
Be sure that the Checkbox to enable IPN is checked!
* in Website Payments Preferences set your Automatic Return URL to:
https://www.yoursite.com/index.php?m...eckout_process
Hope this saves someone some headache!
