Facebook Like Box TOO small.. doesn't show properly…

im trying to add the facebook like box (found on facebook developers page) to my site, but whenever i add a text widget and then add the iframe-code to the text widget box, save and update my page and get THIS result: https://www.shookiemonster.com/shookie-fb-toosmall.png – How come it doesn’t show like it should? what am i doing wrong?

EDIT: also, i tried downloading and install the Facebook Members plugin for WP, but it doesn’t seem to work properly either. which facebook like box plugin would work properly on my WP then? any ideas anyone?

EDIT: And SUDDENLY it got solved…..somehow…… I used the regular facebook like box code and now it works properly…
