Thanks for the Private Message. I just got a chance to look at the site and there's definitely something strange going on. In the head section of your site, there should be a block of code that looks something like:
jfbc.login.logout_facebook=false;
jfbc.base='http://www.sourcecoast.com/';
jfbc.return_url='L2ZvcnVtcy9tZXNzYWdlcz9pZD00MDc5JnBhZ2U9dmlldw==';
jfbc.login.scope='email,publish_actions';
jfbc.login.show_modal='0';
Obviously your values will differ. However, that block isn't there at all, which is causing the problems you mention. If I switch to the rhuk_milkyway template by adding ?template=rhuk_milkway to your URL, those values properly are inserted.
So, you'll need to fix whatever is happening in your template to strip out the code JFBConnect is trying to insert.
Hope that helps,
Alex
