I have the SEO Comments sub-plugin installed and configured as follows:
Merge Fb comments with WP comments ?
NO
Cache option
HOURLY
Add FB comments to html with no diplsay ?
NO
Merge Fb comments count with WP comments count ?
NO
for some reason the backend says "Next cache cleaning: Disabled"
i don't know if it is truly disabled and that is the source of the problem or what.
but if you visit:
http://www.40lovemusic.com/category/blog/
you'll see the first post claims to have no comments, but if you visit the post, it has one facebook comment from last night... which should be included in the count by now.
using your debugger i can track down the raw opengraph data
http://graph.facebook.com/10150978664196341/comments
and verify there is 1 comment on that object.
the second post claims to have 1 comment, even though it has none.
http://graph.facebook.com/10150848651956089/comments
and the third post also claims to have no comments even though it too has 1 (it used to have 4, and did reflect that so the cache must be updating, just not as quickly as I'd like?)

there appears to be no way to manually clear the cache and force a count reload to test the comment counting. that would be a nice feature instead of waiting an hour to see if the cache updates.
looks like i am not the first person to report this either:
http://wordpress.org/support/topic/plugin-facebook-awd-all-in-one-comments-not-merged-between-fb-and-wp
i would appreciate any ideas on how to make the comment counts accurate.
