facebook images & comments

hello

the plugin publishes the post to fb ok.

when i want put pix from facebook to my site through add media / facebook images it says:
Facebook is being really, really slow and not responding to requests in a reasonable period of time. Try again later.

also the comments written from facebook dont show on my webpage and the comments from my webpage dont show on facebook.

any idea?
