Facebook Description Title and Image and All in One Pack Pro | General - All in One SEO Pack Pro Forum | Support | Semper Plugins

I will appreciate your help regarding my following issue.

I have installed the All-in-one SEO pack PRO..

but Facebook cannot take my description or the title that I have specified in the ALL-IN-ONE post Box.
http://www.cyprusorganics.com/…..rectal-ca/

I have read that Facebook needs the following tags:
meta property=”og:title” content=”title”
meta property=”og:description” content=”description”
meta property=”og:image” content=”thumbnail_image”

In order to display the correct description title and photo thumbnail

Do I have to add these manually in the Additional Post Headers box ( all in one settings area) ?? Do I have to add something in my functions.php page in order for the facebook to works correctly with your plug in ?

Thank you for your time,
Georgios
