I'm setting up a store with downloadable products. When an order is placed, two invoices are created. One with the actual price and one invoice with a price of zero. I assume this is not correct.
I don't know wether this has to do with each other, but the order conformation mail is also sent twice to the customer.
Any help is very appreciated
Are you using any third party extension to send Emails? And I would suggest you to verify your cron job setting in cpanel as well. Let me know for further help.
