Hi
I keep
my promise to DiapDealer.
After I introduced -unwillingly- a mistake in one EPUB, I tried to open it with Sigil to perform further tasks. I ask Sigil not to perform any previous control on my ebooks, because some of them are in EPUB3 format and I had been advised to
stay away from such a foolish enterprise.
Sigil refused to open it. It's seemed like a trivial mistake, a punctuation sign ; which should never have been there.This same EPUB is opened without problem with the Calibre Editor.
Please find enclosed the warning message from Sigil, a screenshot of the mistake (with a red arrow) and the EPUB. The EPUB is really a work in progress and was not intended to be seen but I understand it may be useful for analysis.
