How to see more then just 2 comments at time

Sary,
How are you inserting the comment box into your articles? Are you using the Social Configuration area of JFBConnect to automatically add it to all articles? If so, make sure that the Number Comments setting properly set to 50 for all of your views (Article, Category, Featured). If you're using the {JFBCComments } tag, make sure you have the num_comments=50 parameter set.

If none of that works, please post the URL of the page that you're having the problem on, and we can look at the page to see if there's something else we can see wrong.

Thanks,
Alex
