First, thank you thank you thank you! You are a man among men for creating and maintaining Calibre. Bless you!
I installed the Food Network plugin and it works fine. However, from the add plugins page it still shows as "not installed". I tried uninstalling (which it did) and then reinstalling. Still no joy.
No problem for me, but sharing because I thought it might be a bug. Could be a PEBKAC, too. (PEBKAC, most common computer error ever = Problem Exists Between Keyboard And Chair)
