We are also using 1.3.7 at the moment in :-
includes/languages/english/checkout_payment.php
We changed line 20 to:-
define('TEXT_SELECT_PAYMENT_METHOD', 'Please select a payment method for this order, most payment cards can be used if PayPal IPN is selected - In order to COMPLETE your order you will need to click the RETURN LINK once payment is made on the PayPal site.');
Starting on the 16th May then the 17th and the 20th we started receiving the odd PayPal payment without an order being logged by our site. We have logged a support ticket however PayPal said:-
"The Auto Return function may not be the best option if you are relying on return information for back end processing. If your customer makes the payment using the PayPal Account Optional feature, the Auto Return function is temporarily halted as the customer will see a payment confirmation page and be given the option to either a) Return to merchant, or b) Save their information to create a PayPal account. This payment confirmation page is displayed to meet legal requirements for payment processing.
Unless the customer clicks the 'Return to merchant' link, they will not be returned to your site. This can, and does, result in a loss of data for back end processes"
It seems strange that we had hundreds of orders without a problem before this, but added the note to return to the site after payment with the hope it helps. We will see if it works
