Comment+ is not showing comments

I installed the comment+ plugin and followed the steps to setup the facebook app id and twitter app id and also put the hooks in the single page. The plugin is rendered properly on the page, however, when i loged into my facebook(a different account than the one that I used to register the app id) account and leave a comment there, once I hit the submit button, the loading gif shows and 1 sec after, the whole page reloads and then nothing happens. No comment is shown and on the facebook wall, nothing is appended there either. This is it, could you please help me on this issue? Thanks a ton.
