Epub validator error code assistance
Used InDesign CS5.5 to create an ebook as I have done previously. However while past books have been validated, the current book is getting the following error code.
Error code:
Irregular DOCTYPE: found '-//W3C//DTD XHTML 1.1 //EN', expecting '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">'.
Any help regarding what this means and how to fix it would be greatly appreciated. Thank you.
