Kepub is a Kobo extension to ePub. For the most part, it adds a mass of spans used by the WebKit based renderer on a Kobo ereader for location.

The more significant issue is that the content function does not work at all. Whenever I open it on the device, it is completely blank, as if the device does not recognize the headings as headings.
Does anyone have any suggestions on what might be wrong here? 
Would be very grateful for any advice! |
Are you sending the ebooks to your Kobo as filename.kepub.epub? The RMSDK based renderer on a Kobo requires a .ncx file (an ePub2 navigation document) which Standard Ebooks does not include in a kepub which is intended to be opened by the WebKit based ePub3 renderer which uses an ePub3 navigation document (an xhtml document that has properties="nav" set in the .opf file).
As long as the cover image is flagged with the properties="cover-image" in the .opf file, a Kobo ereader will recognize it as the cover image and use it for the thumbnails and cover image for the sleep/power off screens.
