Comments not showing

Your comments are showing correctly – when you click on the article / post title. Your WP shows 10 post on the home page. May be you should change it to show excerpts, by using ‘Insert More Tag’ when you Edit Post. Then you home page will show 10 excerpts instead of the 10 whole articles. When you click on a post title it will show the whole page of the post selected. At the bottom of that is your comments.

I hope this helps

Simple click on the title of your post at home page then you will able to see your facebook comment box at bottom.
