iFrame with Lybsin

Hey there!
The Lybsin site is pushing content with the embedded iFrame player.
The content of this player is not displayed in Chrome and Firefox. Only in Safari.
It displays the content of the player in PREVIEW mode in WordPress but as soon as I’m logged out, the player still doesn’t appear in Chrome and FIrefox.
I suppose this is not normal.
Anyone has an idea?
