As of recent changes to something internal to FaceBook, the FB button may no longer work.
If you look at what is generated by FB's code generator at http://developers.facebook.com/docs/reference/plugins/like/
Note the "show_faces=true"
In the code generated by the module the values are stored as "show" and "hide" and cause the button to fail.
The attached patch fixes this. If you have a current live site running this, you will need to resubmit the form at
yoursite.com/admin/config/fblikebutton/dynamic
and
admin/config/fblikebutton/static
Also check the issue at http://drupal.org/node/1570374 as that may be part of the problem as well. For me, both were required.

ChrisLaFrancis commentedThis issue, #1570374: Like button doesn't display anymore, and #1509770: Locale language affects visibility are all more or less the same thing: the like button stops showing up because Facebook changes its expectations of the parameters that are sent. The patch I rolled for 6.x-2.x here also has an update hook to change the values for the "show faces" variables.
