Heyas! Happy user of this player since we updated our website!
There was a recent glitch though. We updated Jetpack and upgraded to WP 3.5. Since then, our Front Page player is fine, but all the players we had on client pages have dissapeared. Here's an example of a client page, and if you go to 'Current Clients' or 'Past Clients' you'll see an image on the page...normally, the player is directly beneath the image.
I went through the HTML and the short code is still there where it always was...just the playlist itself doesn't appear.
