First of all I'm new to madsonic, just two days of usage, before i was using subsonic, and it worked fine with playlists.
On madsonic I was unable to add tracks to any of created playlists, logs does not show anything wrong, then i click on edit playlist i got "Playlist is empty".
Database result shows the same...
SELECT * FROM playlist
shows FILE_COUNT 0 on all created playlists.
