[Plugin: Facebook Comments for WordPress] Facebook comment is not showing up

Hello, I use facebook comment on this website: kindlemalaysia.com.

My problem is that the comments I enter in cannot show up in the comments section. Prior to filling this bug, I have read the faq, and make sure that all the plugins that are conflicting with this plugin are simply not installed on my server. And yet the problem persists.

Any idea how to fix this?
