An error occurred today when trying to download a fic (
https://www.fanfiction.net/s/691414/1/). The error occurred in both the Calibre plugin as well as on
http://fanficfare.appspot.com (which is my go-to if I have trouble downloading in Calibre for some reason).
On appspot, the error given is simply "maximum recursion depth exceeded."
In Calibre, the error is: maximum recursion depth exceeded while calling a Python object.
