Error message unable to update metadata with calibre

[ananova]

Hello.

I use the Calibre plugin to download fics. Everything is up to date, all the latest versions. But lately when I download fics from AO3 I get a message that the ebook is updated but the metadata isn't. I admit that I am not very knowledgeable about coding, so I'm not sure if this is important or not. Should I do something? This is the detail from one of the downloads.

calibre, version 2.84.0
ERROR: Error Updating Metadata: <p>An error has occurred while FanFicFare was updating calibre's metadata for <a href='http://archiveofourown.org/works/10367655'>Penny Candy and Sparklers</a>.</p>The ebook has been updated, but the metadata has not.

I'm glad you posted the error report because I'd never have figured it
out without the line numbers.

You're seeing that because FanFicFare is looking for an option setting
that isn't there because you've never set any FanFicFare settings.
Which seems a bit rare.

I will fix this for the next release. But in the meantime, you can
avoid it for ever after by simply opening FanFicFare Configure and
clicking 'OK', even if you don't change anything.
