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?
