FB Plugin doesn't work

hi, i downloaded the facebook plugin a of days ago but i can't get it to work correctly, i can't seem to give the extra FB permissions needed for the application to work... WHen i try to give the extra permissions in google chrome nothing happens, when i try it in IE i get a FB poppup saying something went wrong...

i only get to see the widget titles: http://www.wtceagles.be/berichten/
