I am in the process of (hopefully) migrating my online store from Cart66 to MarketPress. This is my dev site to test. I have created some sample products and enabled Stripe in Test mode. I sell large digital files (videos, animations, etc.). They are too large to upload via the frontend. I have FTP'd them all to a directory on my server. I read another post on the forums that said you could use a plugin called Add From Server to add large files so that WordPress/MarketPress can "see" them. I've done that.
But when I do a test checkout as a customer, the whole checkout process works fine, until I get to the link to download my digital file. Then, I get an error message saying the file cannot be found.
I am sure this is simple user error on my part with a configuration somewhere. What am I doing wrong? I have granted support access. The sample product to try is called Black History Month 1 Video.
