I have created my website using wordpress 3.4.1 and, I tried sharing my webpage in facebook. I do not get any thumbnail or the basic blog description in the facebook post. Instead I get “No Title”. I know this question has been asked a number of times in wordpress forums. But, most of them are leading to dead ends. Can some one help me in this regard.
PS: I tried using the facebook debugger (http://developers.facebook.com/tools/debug) I get the following
Error Parsing URL: Error parsing input URL, no data was scraped.
Just like what Niraj said you need to make sure you have the open graph meta tags on your blog. Here is a plugin which will add them http://wordpress.org/extend/plugins/facebook-open-graph-meta/.
