Facebook Comments notification worked only on one page

Hi there,

I’ve created an app from developer.facebook.com for the Facebook Comments Plugin on my site. After set up everything, the comment box appeared and seems to work. The code that i injected to comments.php was <div class=”fb-comments” data-href=”<?php echo(get_permalink()) ?>” data-num-posts=”8″ data-width=”700″></div>

I have three pages on this site, when i test the Facebook Comments notification, i found that commenting on certain page will received a notification in my Facebook account and i can also view the comment in the Facebook Comment Moderation Tool. Screenshot below is my test comment on the page, there’s a Moderation Tool above the comment box.

But when i test comment on another page, the Moderation Tool above comment box was missing, just like i was not the admin viewing the page. Meanwhile, i didn’t receive any notification in my Facebook account and i was unable to view the comment in Facebook Comment Moderation Tool. View the screenshot below.

I had test injected <div class=”fb-comments” data-href=”<?php the_permalink(); ?>” data-num-posts=”8″ data-width=”700″></div> and the comment box appeared in my PC browsers while it disappeared in my Macbook browsers. For PC i tested with Chrome & Mozilla and for Macbook i tested with Safari & Chrome.

Does anyone here know what’s wrong with my code or any other settings? Thanks in advance.
