Great plugin.... seems to be working fine.
I don't want FB comments on all paes and so I have only checked the homepage (which is actually my blog/posts page as I use a static presentation page with my theme).
I used the short code to add comments on a few other pages - but not all of them, otherwise I would have checked the Pages tab in the settings.
The problem is when I click on the blog link with each post and I am taken to the /category/blog page (blog archives). My WP comments remain with each old post but the FB comments box doesn't show up here (because I haven't added the shortcode).
How would I add the php code and to which template.... so that the comment box would show in the blog archives?
