< Torrentz : The Bobcat add-onについてのフィードバック
Fixed in version 1.6.0
There were two problems - the first being that Torrentz changed its protocol from HTTP to HTTPS, causing a problem with reaching the IMDB Api (HTTP).
Second, as you mentioned, imdbapi has been dropped for omdbapi
Buggy
it doesnt work.. may be because imdbapi is not working. its actually omdbapi
