SABNZBD Fail: Cannot Combine OSpaths of Different Platforms

Sonarr stopped working a couple of days ago - it can’t pass to Sabnzbd all of a sudden. When I went to test it fails with the above error message? Anyone have idea what’s causing it?

Great software BTW

Log files from Sonarr would be very helpful, considering we don’t use paths when sending to SAB I don’t have an idea as to what might be causing this.

Also which versions of SAB and Sonarr? Which OS are each of them running on?

ive got same problem sabnzbd latest version sonarr using develop branch both installed on same machine both running as service

Change the “Completed Download Folder” folder setting in SAB’s folder settings to use a backslash instead of a forward slash.

yeah that worked thank you
