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.
Is Smashwords worth it?
I know that Lulu now pushes our books through a lot of channels, but I also know that Smashwords does too... and I'm not certain if they both cover all of the same distribution venues. Has anyone also submitted through Smashwords, and did you find it reached new readers? Are there foreign channels one reaches better? Do you need another ISBN to publish through Smashwords, or do they also used .epub format?
