Hi germi, would you please help me out of this error "Task queue failed at step 5". I have found some posts about this error, but after a long try, I still can't resolve it.

In my site, the html5 player works fine in playlist mode and also song mode. but with the browsers like firefox which doesn't support html5 player. I get directly "Task queue failed at step 5: playlist could not be loaded" in playlist mode, and in song mode, i can see the player, but it can't play correctly the music.

here is the lien:
