I setup a download option within the checkout, but the download links that are given to the customers open a blank page. They worked when I first setup the galleries. I am now getting messages from all my customers stating that the links don't work and I can't figure out why since I haven't changed anything. Today I tried updating both WordPress to 3.5.2 and Image Store from 3.2.9 to 3.3.0 but the same issue is still there. Is there a fix for this?
