Well, I've seen this explanation here http://wordpress.org/support/topic/plugin-facebook-comments-importer-older-fb-posts?replies=3 on importing comments from more posts on facebook. But it's not working, I changed the number 30 to 100 (I even did a search on the document and tried chaning the number 30 on line 101 too just in case) and it didnt work. It didnt import not even 1 comment more than it did before.
And, were the older posts supposed to show up on the list that the plugin settings page gives us? Because it doesn't either.
Any help is appreciated, thanks
