console errors… plugin conflict

Hello,

I discovered a conflict between your plugin and SoulNav (http://gingersoulrecords.com/blocks/soulnav)–an extension for the Headway theme. When I install SoulNav with mb.YTPlayer active, much of the content of my site (http://somethingreal-film.com) becomes invisible (although the video still plays).

If I deactivate mb.YTPlayer that problem doesn’t occur. I contacted the SoulNav developer and they pointed out the following JavaScript errors that may be causing the interference:

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

Am I doing something wrong to get the above errors? And do you think they could cause a conflict with other plugins? Thanks!
