Brian,
Let me see if I can help you out. First you’ll want to go to the Appearance section of your WordPress control panel and select widgets. Then drag the Foundation Facebook Widget to the sidebar of your choice (it’s in the Home Top in the demo). Once it’s there, you’ll want to paste the URL to your Facebook page into the box for it and save your changes.
That should add a like box to your site. Facebook does limit the like box to what it refers to as “pages.” At this point in time, they don’t allow the like box to work with groups or personal accounts. If they change that, then we’ll change that too.
Thankfully it’s no longer required to have an App ID for the like box to work.
If have any trouble, let me know,
Bill
