[Plugin: Add Link to Facebook] Plugin: Add link to Facebook – could not get it to install

May I join in with the same problem? I added the Add Link
to Facebook Plugin to my site http://www.aohkelly.org. I followed the setup guide until I was reminded to Configure. I clicked the link to set up the App but I couldn’t locate the place/page to do as you recommended in the setup guide.
Any help appreciated! Thanks.
