WordPress ? Support ? How-To and Troubleshooting Youtube Thumbnail on Faceboo

I’m not sure if this issue is related to the jetpack feature of publicize or a issue with the Ari theme. I also posted this issue in the Jetpack forum.

When publishing a post that contains a YouTube video (inserted into the post using the YouTube embed code), and nothing else (no text/images), from WordPress to Facebook using the “publicize” feature, the YouTube thumbnail does not show. I would like to show the video thumbnail in my Facebook post. How can I do this?

My website is ninjasensei.com

My workaround was to take a screenshot of the video thumbnail and set it as the featured image. It then showed in my Facebook post but when I navigated to my page it displayed next to my video messing up the formatting. I then deleted the featured image. It still shows on the Facebook post and not on my blog post, which is what I want. I know there is a modification I can do to the single.php page to remove the featured image from the post but I do not have the code that others have referenced.
