FreeBSD Handbook epub formatted incorrectly?

[Remy Zandwijk]

Dear Guru's,

I downloaded the epub version of the FreeBSD Handbook to my iPad mini, in order to read it while travelling. However, when opening the epub in iBooks on the iPad, I get the error message: Cannot Open "FreeBSD Handbook". It is formatted incorrectly, or is not a format that iBooks can open. In iBooks on macOS however, the epub opens just fine.

Any thoughts on where to look to fix it? Of course, I could just take the PDF version of the handbook, but that lacks resizing the font conveniently.

Cheers,
Remy
