Serious Problem with Comments

Hi,

My website is https://www.bollykings.com

I recently installed and activated the intensedebate plugin and all was working smoothly until I realized that my comments were acting very weird!
Please see this page:

https://www.bollykings.com/shah-rukh-khan-and-aamir-khan-compared/
and this page :

https://www.bollykings.com/recent-akshay-kumar-movies-is-tees-maar-khan-a-hit-or-a-flop/

Both the articles had a good number of comments (63 and 25 each) and after I installed the plugin, the comments disappeared!! All of them!! And this has been happening on nearly all my other articles as well which had comments on them.

This is the first time that such behaviour is happening on my blog! Can somebody please help me out?

thanks!
