I’ve compiled my Scrivener file into .mobi and .pub.
Amazon has accepted the file without any issue
But Kobo asks to fix a problem (attached). Is it possible to use Scrivener to fix that? And is it a problem generated by Scrivener compiling the file?
It looks like a bad link in the content itself to me. I’d open this ePub up in Sigil and load the referenced body114.xhtml document, checking around the position indicated (it’s not always accurate) for a link. Once you find the spot, you should be able to go back and fix it in Scrivener.
