At this time, we're investigating the problem and looking for a solution.
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.
We've also created this Forum Thread. Post questions here and we'll do our best to respond and assist.
Lulu and eBooks
Who is Lulu?

Through our Internet retail site, retail partners, and global print network Lulu has created a one-stop shop for the ultimate in publishing freedom. You pick the price, market, and medium. As a Lulu author, you have complete control over your price and content. You earn 80% of the profit or more when your work sells.
You are the new face of publishing and you are in control.
What are eBooks?
EBooks are electronic, downloadable books that can be accessed on an ever-growing number of eReader and handheld devices, like the Amazon Kindle, Kobo, Apple iPad and iPhone, Barnes & Noble’s NOOK, Android tablets, and your home computer. Millions of readers purchase eBooks each day. By publishing an eBook, you can more easily share your knowledge and ideas with readers all over the world.
Once you have read and followed Lulu's guidelines for preparing your manuscript, the Lulu EPUB Converter can be used to create an eBook in EPUB file format. These guidelines do not guarantee success on your first conversion attempt, but by following these instructions, your chances of success are greatly improved.
How Do I Sell My EBook on Sites Other than Lulu.com?
As a Lulu author, your eBooks (EPUB and PDF) can be published and offered for sale in the Lulu Marketplace at no cost to you.
Authors with bigger ambitions can assign an International Standard Book Number (ISBN) to their eBook (EPUB) making it eligible for distribution to the iBookstore and the Barnes & Noble Nook store in addition to the Lulu Marketplace. This option is available to authors using a free Lulu ISBN as well as authors who choose to bring their own ISBN or purchase an ISBN directly from Lulu.
All eBooks in EPUB format that include an ISBN are automatically submitted for technical review prior to distribution to retail partners. LULU DOES NOT PROOFREAD OR REVIEW YOUR CONTENT; however, we must ensure your work meets the technical quality controls required by our distribution partners. This review focuses on compliance with distribution guidelines as well as the technical aspects of your work, such as the file size, title, description, categorization, image quality, and table of contents functionality. For more information about eBook distribution requirements, see eBook Retail Distribution Guidelines.
If there are any problems detected during the technical review, you will receive an email listing the areas that require updating. Once you have addressed these issues, you may resubmit your work for a follow up review. If your work meets all guidelines and there are no technical issues, your work will be passed along to our retail partners who will conduct a final technical review before placing your work on their sites.
