[Plugin: Lightbox Plus] X-Frame-Options Refusal Error

Trying to display a youtube video that I uploaded using this plugin. Secondary lightbox functionality is disabled. Console reports this error:

Refused to display document because display forbidden by X-Frame-Options.

I have 2 videos on the page the first of which works but when bringing up that video, console reports:

Unsafe JavaScript attempt to access frame with URL http://staging.example.com/ from frame with URL http://www.youtube.com/v/<snipped&gt;. Domains, protocols and ports must match.
