does not work

You are using the shortened link; i.e.: “http:/youtu.be…”
Try and use the link format in the examples we provide here: http://ww.wp.xz.cn/extend/plugins/youtube-embed-plus/

That is, try the standard YouTube links: ” http://www.youtube.com/watch?v=…”

If that doesn’t work, then email us to get faster help service.

Thanks,
