I have a problem with the Like Box - its connecting well with the fan page, showing correct number of likes, but in the box showing only one face... I know its not an issue of users permissions, because the page has more than 300 likes, and some of its users faces are appearing in another like boxes.
Anybody has an idea what can be wrong?
I've just figured it out - the problem disappeared when in the field 'Facebook Page URL' instead of 'facebook.com/MyPageName' i've put 'facebook.com/pages/MyPageName/PAGE_ID'
