Thank you for submitting the question here. Regarding your question: By default, EShop does not support to upload epub file extension I think. To change that, please go to EShop -> System -> Configuration -> Option tab, at "Allowed File Types" and "Allowed File Mime Types", please add type of epub file extension there, then you can upload it normally.
I actually already tried, what you suggest (see attached image) but it did not help. You can se in the image how I did it, but maybe this is the wrong way?
I also tried to put it this way "text/epub" but that did not work either.
Best regards, Morten
