Why is my ePub encrypted (according to book proofer)?
Having managed to get one ebook book accepted (ePub) and Amazon (.mobi), I thought it would be easier this time round – and I’ve hit a completely new problem. The export process is fine and it validates with the IDPF online checker. But then I hit a problem – Book Proofer won’t open the epub file to sync to iPad as it says it is encrypted.
I'm using Indesign 5.5.
I’ve not knowingly done anything different this time. I’ve even changed the fonts I was using to be the same as I used in the last successful one. (And I've pasted the text into a completely new indesign file).
I don't know what it is I've unwittingly done to encrypt the file. Sounds like the sort of thing I’d never have found if I’d been looking for it!
Can anyone advise? The simpler the better!
