Do trakt, anidb, anilist work?

I do not use trakt, so I can not test this. anidb and anilist do work.

Did you try this again later. As I suspect that one of the two imdb requests failed.
We run two commands
imdb_api.get_title(imdb_id) and imdb_api.get_title_genres(imdb_id). And only the second one seems to fail for you.

I can handle the error. But that means it will never be able to get the show genres for you.

Ooh one thing you might try. Is going into /cache/ folder and remove the file recommended.dbm.*.
Then restart medusa and try again. Could be that the request error was cached.

This fixed the issue. Thanks!

In the next version it will not be able to cache "bad" requests/responses.
