Purchases with a Paypal account with Paypal Payments Standard are auto returned correctly, confirmation of payment is received by the store, email notifications are received by the store owner and customer.
Purchases made without a Paypal account with Paypal Payments Standard using a Credit Card are not auto returned and confirmation of the payment is not received by the store, hence no emails are sent confirming the order.
However, payment is processed, and both parties receive Paypal notification although this obviously contains no details of the purchase (shipping fee, order number, etc).
We have tried turning on Credit Card in the options and this made no difference.
At the Paypal end, we can and have turned off the options allowing transactions without a Paypal account, for the time being, but we haven't tested credit card transactions through an existing or newly created Paypal account.
(incidentally successfully is missing an s in the payment status)
In the shipping email that is sent, [shipdate] does not insert replace, hence the email is sent with [shipdate] as opposed to the ship date.
