Hello (and help!).
Having successfully published from Scrivener (from an iMac running 10.9.5) to KDP, I am trying to do the same on KWL, but keep getting ‘an error occurred during conversion’ and the signpost to the EPUB Validator., which then gives this message (screenshot also attached):
ERROR OPS/content.opf 41 38 date value ‘2015/06/15’ is not valid as per w3.org/TR/NOTE-datetime: [For input string: “2015/06/15”] is not an integer
Unfortunately Kobo have not been of much help. I’ve searched online/here but found nothing similar to this, and I do not possess the level of knowledge to ‘figure it out’.
If it helps, when I create the .epub file and save it to my desktop, the iBooks icon appears on it. This just happens automatically, without me doing anything.
Also, I tried to upload a .mobi file (as Kobo says it can convert them), but exactly the same error message occurred
Help with this would be much appreciated. Thanks!
