Plugin causes error with YouTube API (www-widgetapit.js)

Hi,

We’re using your plugin to make videos on our site responsive. I’ve noticed however that sometimes — I think on the second load of a page — the plugin causes an error with the YouTube API.

For example, on this page http://www.ibiology.org/ibioseminars/microbiology/david-baltimore-part-3.html

If you load it once or twice you’ll eventually see this error:

www-widgetapi.js:98 Failed to execute ‘postMessage’ on ‘DOMWindow’: The target origin provided (‘https://www.youtube.com’) does not match the recipient window’s origin (‘http://www.ibiology.org’).

The error goes away though when I deactivate the plugin.

Any thoughts? Thanks!

– Daniel
