Stream not showing

Hi

this might be a facebook thing or a plugin thing, not sure (as I used another plugin before which worked but seems to have stopped working a few days ago now.

in short, the facebook stream does not seem to display anymore .

if put the widget here
http://www.lunasa.ie (at the bottom of that page)

any ideas ?

thanks
