I read a lot of WebNovels (found on freewebnovels, novelfire, novelbin, etc.)
If they are short and I am at my computer I read a lot of them online. But if they are long, (quite a few are 500+ chapters, and some of the Asian ones are 2000+)
For the long ones I had been using a Chrome plugin called WebToEpub to download them, and read off line or on my kindle after converting to kindle format.
99.9% of the time I have no problems.
But recently I downloaded 2 novels, and Calibre could not handle the epubs produced.
The first, it could not view, edit or convert it.
The second I could view it (viewer opened it and I scanned the complete book) but could not edit it or convert it.
I assume some string of text or code is giving Calibre a problem.
Downloading the same books from a different sources gave the same results.
Which would imply it might not be a formatting error as different sites use different css styles? So another site should work if the first did not?
In any case, the first book was:
Dungeon of Lust: Managing Otherworldly Beauties by LowkeyCrow from novelfire.net
Long Error message from the first book:
