Conversion to epub missing parts on Kobo

[Wrongway]

I have grabbed a story from a fan site using the FanfictionDL plugin. I thought all was fine as it reads ok in the Calibre reader. However when I side load the epub to my Kobo Mini or Kobo Aura HD big chunks are missing out of chapters. I tried on a Kindle reader in mobi format and that seems fine. It seems to be the end several pages of a chapter that is missing when loaded to the Kobo. The text resumes at the start of the next chapter. I don't know if its a factor but the new chapter starts with the chapter title in the same font but larger and followed by a copyright symbol (c in a circle), and a date. As Calibre viewer shows the file correctly I dont think it's the FanfictionDL plugin or the Calibre conversion thats at fault. I am starting to suspect something in Kobo's software. Anyone any ideas?

What f/w is on your Kobo?

Can you share the ePub so others can try it too?

I have seen something like what you describe when there were some errors in the HTML. The epub renderer on the Kobo devices is not very forgiving for errors in the HTML. From memory, the problem was caused by incorrect nesting of tags. Something like the following would do it:

<i><b>Some text</i></b>

Open the epub in the calibre editor and run the "Check book" tool. It should show any errors and you can fix them.

@PeterT the firmware on the Kobo is the latest. It looks like I have found the problem with the help of davidfor

@davidfor Each file has the same error reported when I run the check book tool which I didn't even know existed! So thank's for that. The fault is
Parsing failed: Opening and ending tag mismatch: line 223 and div, line 223, column 11****[OEBPS/file0001.xhtml]

So as you say, it's probably incorrect nesting of tags. When I ran an automatic correction it cured the problem. I have to work out if FanfictionDL is adding the error or the error is in the original HTML which I suspect is the case.

@Wrongway: For future reference, saying "the firmware on the Kobo is the latest." is useless; Kobo stagger releases of f/w and there is no guarantee at all that your device has the latest release that has been released.

Sorry Peter. I have had the Kobo's a week the Aura less than that and they both did a firmware update when I registered them. I presumed that would have been the latest. The Mini seems to have version 2.6.2 and the Aura HD has 3.2.0.

The way FFDL constructs the epubs means that "files0001.xhtml" is the first chapter in the story. Or the full text for a single part story. So, odds are it is on the site. If the site is correct, report the error in the FFDL thread with the URL of an example that has the problem.
