Home page not ticked but still appearing

Hi,
I’ve unticked the box for home page but it still shows on my homepage. Not the end of the world but Facebook debugger gives me this error code:

Object at URL ‘http://www.mybizperforms.com’ of type ‘article’ is invalid because the given value ” for property ‘fb:app_id’ could not be parsed as type ‘fbid’.

and the only instance of this property I can find in the source code of the index page is i

<!–Facebook OpenGraph Slick Social Share Buttons –>
<meta property=”og:site_name” content=”My Biz Performs”/>
<meta property=”og:title” content=”My Biz Performs”/>
<meta property=”og:url” content=”http://www.mybizperforms.com”/&gt;

<meta property=”og:image” content=”http://www.mybizperforms.com/wp-content/uploads/2012/09/follow-me-twitter-icon-feature.jpg”/&gt;
<meta property=”fb:admins” content=”” />
<meta property=”fb:app_id” content=”” />
<meta property=”og:type” content=”blog” /><!–End Facebook OpenGraph Settings –>

So I wonder what it means and how to rectify it?

Many thanks. LOVE your plugin, played around with so many, so glad I found yours. Just perfect.
