Even after changing it back to how it was it still says that.
edit: uninstalling and reinstalling the plugin fixed it

You never need to change anything inside the plugin zip file. In the FanFicFare configuration, there's a tab 'personal.ini'. Click the button for 'Edit personal.ini'. Make your config changes there.

Images failing are common and can be ignored. The relevant part is:

The failed chapter URL is https://forums.sufficientvelocity.com/posts/

Searching the source for the index post shows there are two chapter posts with that bad URL:

Thread 10, Part 2 - Approaching Evil
Girl Talk with Tomo [77]

Thread 10, Part 6 -The Circus
Actors Upon A Stage [11]

I suggest you ask the author/index maintainer to fix those.

Those are part of normal operation and can be ignored.
