lulu formatter says its an epub but it remains as a .docx
I have been fairly successful in formatting my own epub by using the Lulu epub creator and feeling my way thru errors.
Suddenly, a few days ago, the epub creator went thru the motions, got to the "you have an epub, check table of contents"
But then instead of labeling this in "My Files" as a .epub it constantly calls it a .docx no matter what changes I make to it
Put in a help request to Lulu but so far no response. Anyone have any ideas. I hope its just some silly thing I'm missing!
