I'm setting up a site that uses eShop (and other ecommerce plugins). We were having a Paypal issue with a misconfigured currency. But now we've solved it, and we find that while the payment is made and the sale appears as done and delivered (a digital item) no email is being received by either the admin or the customer. So the digital item can't be downloaded.
I've been through the wiki to check the configuration, and I can't see where we're doing it wrong. Any possibilities I should check again?
