Hi Im new to download manager and trying to set it up to be able to sell digital printables. I am confuse don how to set up the payment gateways , paypal and stripe. Also when I add the featured image for the file it comes twice on the page. Is there not a thumbnail version that goes next to the download button? Please help me with setting it all up, or if you can direct me to a start up guide/ youtube tutorial. I am using the free version. Thanks
