rafiqdivision on "Audio Player/Playlist not working"

Hey folks -
I just updated to WP 4.5.2 and now the audio player isn't working. When using the shortcode [playlist ids="1226,216,222,221,220,217,224,225,226,2183"] the page just diplays a blank gray box. Interestingly, in the Visual Editor the player displays exactly as I imagine it would.
I'm using a child theme (Responsive), and I wonder the issue is within the theme, somewhere?
Any help would be appreciated. You can see the issue on this page (scroll down a little, please)
