Error 500 on prestshop order payment
I have installed and configured PS plugin, everything is fine until I complete the order, when i send order, instead bring me to payment page, it shows an ERROR 550.
The order is registered in admin area, customer and merchant cannot receive any email, log is not written...
Here the apache log:
