Facebook fan box?

i want to add Facebook like box in my word press blog . where i put this box coding. yesterday i add coding in text widget it cannot display. what is the reason?

 

Are you using the right code? http://developers.facebook.com/docs/reference/plugins/like-box/

What do you see when you look into the source code?

 

try using the facebook social plugin. copy paste the code to where you want the plugin to appear, usually at the sidebar.

 

You are right! The code works when input in the text widget.
Try generating the code again and remember to paste the FB page URL on the facebook app to generate the code.

cheers
