I embeded these YouTube Videos using Artiss YouTube Embed By David Artiss. It was a great Plugin for WordPress YouTube videos but it was taken over by another developer and it’s not as well liked any more. Besides which, with the new version of WordPress you can now embed YouTube videos automatically just by pasting the shortlink into a Page or Post.
IDK what happened but David Artiss is no longer the Developer for the YouTube Embed plugin and you can now embed youtube videos easily in the new version of WordPress so you don’t even meed a plugin for this.
