I think it’s a browser problem, with my Chrome installation
In Firefox, it fills the entire space, but in Chrome, I also see a blank space at the bottom, but I believe that is a problem on Facebook’s end.
I read that “The minimum supported plugin width is 292px.”
Default value is 200.
http://developers.facebook.com/docs/reference/plugins/like-box/
I’m not able to make it anything other than what looks to be 100%/full width of the template. I’ve tried 300, 450, and 700 – no luck.
@ecleath Could you start a new thread if you are having issues with the Jetpack Facebook Like Box widget?
I am able to “close the bottom” of this widget by manipulating the height — 475px looks good in my theme — but then I get a whole other issue with those fan images (what Jetpack calls “faces”) being displayed in a weird way: the last one gets a line all its own, followed by empty spots!
