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.
Relative Intelligence, I think.
I am a relatively intelligent person but this one has me stumped--and it has happened numerous times:
I upload the newest edited file into my projects (after I have removed the older one). I witness the little whirligig-gear-thingy going 'round and 'round while 'it' says to wait a few while my internal files are being created. It also tells me I will get an email when it's done, which I do. Three hours later, I go into the email and go back into Lulu via the email link and it says, "The page you are looking for might have been removed, had its name changed, or is temporarily unavailable."
So, I go into the site directly from my browser to find the data file there (under my files) but no converted file into ePub. And, like I said, it has been three hours, at least. Please, what's wrong with this picture?
PS, I did this three times. Each with the whirligigs, each with an email confirmation received. [This is where I type in my emoticon sad face with me pulling out my hair!]
