My customers use to receive an email invoice when they purchased something, now they aren't receiving the invoice. I know Zen Cart automatically emails the customer a copy of their order details when the order is completed on the website after payment is made - but they aren't getting this anymore.
Everything in our store is downloadable, so after payment has gone through, the next screen they get is the download screen, which is good that they can still get their downloads, but they would like to get the email again.
Any suggestions why this is happening or how to fix it so they can get the email invoice again?
