I am just starting with using Sigil. I want to edit existing eBooks I had originally converted to epub files with Calibre.
When I open the epub it just opens with a blank page called "titlepage.xhtml" - I can't see the contents of the file I opened anywhere.
Sigil version of 1.5.1
I am using Mac OS High Sierra
I have been searching this forum for tutorials and similar problems but can't find anything so making a post.
Any ideas what I should do next?
Thank you very much
