I just viewed the source of the page and searched for 'facebook-jssdk'. When I saw it was in a spot outside of a <script> tag, I knew that was the problem. No magic hereI know how to see page source and use firebug but am not aware of how to find that code as you did.
In the image, I don't see an error message, but assuming it won't let you publish with something about not having a Channel Owner. If you click into the Channel, there should be an option to select the Channel Owner, where you select a user from your site that has authenticated with Twitter or LinkedIn. If that's not showing or working properly, please post an image of the channel configuration screen so we can understand what you see.I cannot get the twitter or linkedin social channel to publish. There are no options for Channel owner. (see img 1)
