So when you add a playlist and re-scan, do you see the playlist at all? Or is it in the library, but contains no songs?
One of the things that I got a little confused about with the latest nightlies is there are actually 2 config values on the Web Interface. 1 for “Process Playlists”, and another for “Process m3u files”. I have them both set to “Yes”.
I’m also still running svn 1545, so svn 1571 may have changed this.
