Question
validating error in epub
i’ve exported an epub using Indesign CC 2015, reflowable txt. When I run it through EpubCheck I get the error: ERROR (HTM-004) : Irregular DOCTYPE: found '', expected '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">'.
How can I fix my epub in order to get no errors in EpubCheck? I uploaded the epub to a selling point and it didn’t get accepted.
Yours sincerely, Joanna
