I have two online stores, one using v138a version and the other 1.3.9e
Both have been working fine for many years.
I'm having problems lately with the first version where customers order items, pay for them with paypal, I get a message from Paypal saying I got paid, however no order is shown on the store, the stock quantity does not change, the customer history does not show any order has been made.
I've tested with a dummy user, confirmed it is not working.
It does not happen with my other store using ver 1.3.9e
When I set IPN debugging I get towards the end of the log file /includes/modules/payment/paypal/logs:
IPN WARNING :: Transaction was not marked as VERIFIED
IPN FATAL ERROR :: Transaction did not validate
on 1.3.8a version I have: PHP Version: 5.2.17 (Zend: 2.2.0)
on 1.3.9e version (where it works fine) I have: PHP Version: 5.6.40
Any idea what might be the problem?
Thanks,
Amnon
