Facebook Social Plugin Comments not shown when directly linked to?

问题

I just set up Facebook social plugin comments on my site, but I'm having a little trouble with them. When I get a notification saying that someone commented on something I commented on, if I click on that link I see no comments, but if I reload the page without the ?fb_comment_id=... then I can see the comments.

For instance:

http://www.5crideshare.jessepollak.me/rides/17?fb_comment_id=fbc_10150513336718064_21937866_10150513339773064&ref=notif&notif_t=open_graph_comment#f82002554

shows no comments, but

http://www.5crideshare.jessepollak.me/rides/17

shows comments.

Any ideas on what might be causing this?

Thank you very much,

Jesse

Because Facebook supposes that they are two different pages. While you are adding the plugin to your page, pay attention to data-href value. Make your data-href value constant for the same page, although it may be requested with different URLs with extra querystrings.

When I look at your page source, clicked from notification:

<div class='fb-comments' data-href='http://www.5crideshare.jessepollak.me/rides/17?fb_comment_id=fbc_10150513336718064_21937866_10150513339773064&amp;ref=notif&amp;notif_t=open_graph_comment' data-num='{:posts=&gt;2}' data-width='500'></div>
</div>

On this page, data-href value should be without unnecessary querystrings. It should be like this same with clear one: http://www.5crideshare.jessepollak.me/rides/17
