I received following error when uploading my Calibre converted epub file.
1st I get this error
1 OPF file failures
1 instance(s) similar to The file '%1$s' does not appear to match the media type %2$s, as specified in the OPF file. :Format specifier '%2$s'
1 Packaging failures
1 instance(s) similar to Wrong file extension for image. The image is a '%1$s' file but has the file extension '%2$s'. :Format specifier '%2$s'
Then when I fix the errors listed above I got the following
there was an error when parsing the epub version: [version not supported].
Strange I used the free epub conversion software on Kobo's website how did they convert it to an unsupported format? So I am assuming it has something to do with my original file. I tried saving as docx and odt.
My searches show this may actually be an old problem that should have been fixed. Does anyone know what that fix was? I feel a conspiracy theory coming on but if you guys suggest my skills are limited and I should just pay the $89 for Kobo's third party conversion service Aptara I won't be offended.
