We're aware of an issue with converting some DOC, DOCX, ODT, and RTF files to EPUB through our Ebook Wizard.
We've created this Forum Thread with some workarounds and advice to assist you in publishing you ebook.

Little help with one Warning...

"Your EPUB file passes epubcheck-3.0.1, but we recommend you make a few corrections before proceeding."

"WARNING: [email protected]:uid content 'null' should conform to unique-identifier in content.opf: 'urn:uuid:e2e22071-7963-49a8-8d80-599e3e3ce47d' in OEBPS/toc.ncx"

This is from a Lulu generated EPUB that was downloaded, one or two small edits made in Sigil, then re-uploaded to Lulu . . .

Anyone get me started..?  I'm almost there, I can smell it . . .

    Back to the grindstone.   Many thanks.  Smiley Happy
