Is there anywhere on this site that provides explanations in English for the cryptic error messages?
Better yet, anywhere with steps on how to correct them?
I got the following errors while trying to validate my ePub file:
|[ERROR]OEBPS/content.opf: 11,14: element "metadata" incomplete; missing required element "dc:title"|
|[ERROR]OEBPS/toc.ncx: External DTD entities are not allowed. Remove the DOCTYPE.|
[ERROR]OEBPS/toc.ncx: External DTD entities are not allowed. Remove the DOCTYPE.
I used InDesign CS6 to generate the ePub file and then tweaked some problems both in Calibre and Sigil.
As per a reply to someone else, I've gone into the metadata in Sigil to add the "dc:title", but I still get the error message that it's missing. And I haven't got a clue what the second and third errors mean.
Any help would be appreciated.
