Works on pages but not posts

Hi,

Great plugin, works like a charm on my home page template, but I can’t work out why it is failing to fire on single.php.

Here’s link to homepage:

Here’s a link to a post:

I have tried deactivating the plugin, and the youtube videos are being pulled in fine, so no problem there.

Any help would be appreciated.
