Facebook Like Button Widget not showing up

On Facebook I have my AppID, my AppSecret and my App Namespace. I have entered all this info into the Facebook General page on the WP Admin.

I am trying to get the Facebook Like button to show in my sidebar. I can invoke the Addthis Widget under my posts and I can add other, standardized WP widgets to my sidebar, but all Facebook widgets fail.

Here’s what’s in my functions.php

function dp_widgets_init(){ /* using this for sidebar widgets, etc*/
	register_sidebar (array (
		'name'=>__('Sidebar Right', 'dp'),
		'id'=> 'sidebar-1',
		'description'=> __('Main page sidebar', 'dp'),
		));

	register_sidebar (array ( /*using under individual posts */
		'name'=>__('Sidebar Subpost', 'dp'),
		'id'=> 'widget-1',
		'description'=> __('Under Post Social Plug', 'dp'),
		));
}
add_action( 'widgets_init', 'dp_widgets_init' );

in my index page I call this…
<?php dynamic_sidebar('widget-1'); ?>
and it works great!

in my sidebar.php, I call this…
<?php dynamic_sidebar('sidebar-1'); ?>
and it fails… but only when I use a Facebook widget. The calendar, tag cloud, etc.. all work..

YES: I have checked off “show on ‘home’, ‘archive’, ‘post’, ‘page’, etc etc, so in theory this ought to work throughout the templates.

Also: I noticed the like button through the admin has a minimum pixel width of 285 pixels, but when you add the widget and specify the dimensions through the drop-down on the widgets page, the minimum is 260 pixels.

That’s a lot less of a problem to me than the plugin…
