[Plugin: Social] Issue with posting comments

I am not able to see the sign in with Facebook / Twitter to post comments for articles on the blog

my post is here – http://toadityakumar.com/new-post-to-test/

Its all blank where it says “profile”. I have activated and signed into my facebook profile in the settings of the plugin.

Why is this happening?? Any clue anyone?

Thanks
Aditya
