qBittorrent official forums

For some time now my qbittorrent is giving this error message. It is not accepting some torrent files that I had already added to it is giving the error that is in the images.

Well, quick Google threw me this: https://www.reddit.com/r/qBittorrent/co ... &context=3

I'd also check Execution Log and try to run qBittorrent from Terminal, see if that gives more info.
Usually when its something cryptic, I checkout the git source code and grep for the message. Usually I find the thing after like 5 minutes.
