If you've encountered this issue while converting your file, we suggest attempting to create and upload an EPUB directly to our system.
While there are a number of EPUB conversion options, Calibre (Download Here) has shown the best results for creating an EPUB for the Lulu system. Please review their extensive Help resources (Found Here) to create an EPUB 2 that our system can validate.

Unknown Error Message when trying to convert to epub
I have repeatedly gotten the message that an unknown error occurred in the conversion of my document and have been referred to read the instruction document on how to format. I have gone over it, made changes and reuploaded probably 20 times and I have made changes in my document that I thought might be the problem, but I am running out of ideas to get past this "unknown error". I have even started over, by pasting my manuscript into a new document and reformatting it. I am running out of ideas.
Is Lulu's software having issues? Anyone else having these problems? I have written to Lulu support but have yet to hear anything back from them. It's so frustrating to be told to fix an unknown error. How am I supposed to fix an error when I don't know what the error is?
