I've done several projects in older versions of Sigil but now I have the latest version and in both Nook and Apple I'm getting the error "missing container.xml file". I've looked this up and created one by hand - but where the heck do I put it?! And why isn't Sigil creating it automatically? Do I add it as a Text file or somewhere else?
Thanks so much for any help! This is stopping the whole book upload process
