I went to one of my albums,
http://jalbum.net/en/browse/user/album/1891864, and used the share option for Facebook. It works there but then that skin is Projector. For Lucid, however, the share function behaves differently in the way I perceived; which turns out to be a misinterpretation of what I was attempting to do.
What I interpreted with the way the "Control bar" and sub-section "Social" behaves with the Facebook App ID was that if I provided the Page ID where I wanted people viewing to post the share rather than selecting a Page or Account of their choice, the skin would provide the correct coding for that Page. After attempting to duplicate the error and could not, I discovered and surmised after reviewing the link you provided that one would have to be versed in understanding the process as a coder would. Thus, I can fix my issue easily though someone else who really doesn't want to deal with coding nor becoming a true developer might assume something completely different just as I did. Thus, this part of the Lucid Skin is more for an advanced user who really can understand the parameters necessary for this Facebook App ID to work. I see the bright red star you have on that section though have no clue what it means since it isn't displayed anywhere else.
I'm not interested in creating a Facebook App at this point in time, thus I'll remove that information from the section which generated that error message though could not recreate it 30-mins earlier this evening.
