My website has two different payment methods: bank transfer and credit card. Automatic order email works fine when bank transfer is selected, but it does not work with credit card (you must go back to admin and send the order email manually to the customer). When I open Order view (in Sales), the message "the order confirmation email is not sent" appears.
Order status is complete on the admin.
To enable credit card payments on Magento I have installed my bank "official" extension, and the full card payment process is working ok at this time.
So any help is welcome to get automatic order emails sent correctly to the customer. Thanks.
