WP 4.4.1: No playable sources found
after the auto-update auf my site to WordPress 4.4.1, JW-Player stopped working. All I get now is "Error loading player: No playable sources found" as you can see here: http://www.rockin-accordions.de/audio_video/
I use the "JW Player 6 Plugin for Wordpress" in version 2.1.14 with playlists and html5 players.
What might be wrong here?
Thanks for your help,
