I converted an epub2 to epub3 and now get these errors from epubcheck:
ERROR(NCX-001): 9781094414577_epub3.epub/OEBPS/toc.ncx(-1,-1): NCX identifier ("055C55CF-49B4-494B-877B-359A7F23C9B4") does not match OPF identifier ("urn:uuid:055C55CF-49B4-494B-877B-359A7F23C9B4").
ERROR(RSC-005): 9781094414577_epub3.epub/OEBPS/nav.xhtml(6,12): Error while parsing file: Element "title" must not be empty.
The identifier numbers are the same except for that prefix. What am I supposed to change?
The tags in the toc.ncx
<meta content="055C55CF-49B4-494B-877B-359A7F23C9B4" name="dtb:uuid"/>
The tags in the content.opf
<dc:identifier id="e" opf:scheme="UUID">055C55CF-49B4-494B-877B-359A7F23C9B4</dc:identifier>
This book previously passed epubcheck without getting an error.
I'm not sure what I'm supposed to do about nav.xhtml because there is no such file listed in Sigil's book browser. Any advice there?
