I'm trying to upload my Epub to Barnes and Noble for the Nook. I get and error message that Pre-Paginated Epub files are not supported. I cannot figure out how to fix this. Can somebody please help?
It means they only support flowable EPUBs, while PubCoder exports fixed-layout EPUBs https://docs.pubcoder.com/pubcoder_epub.html#reflowable-vs-fixed-layout
