Demo pages not working

Hi everybody,
I’ve just installed the newest plugin version and I know that the shortcode has changed.

I would like to see some shortcode samples but the demo pages don’t work (i.e.: http://poselab.com/en/youtube-channel-gallery-demo-with-title-and-thumbnail-at-the-bottom/)

Can you please help me?
