W3 Total Cache and Facebook Open Graph Errors

Hello,

I am trying to get Facebook to share my post correctly by using Open Graph tags in my header.php file.

By that, what I mean is when someone clicks the “Like” button on my post, I want the featured image, description and title to show up on the persons page who “Liked” it.

All I get now is a URL with no description or image.

When I use the debugger at https://developers.facebook.com/tools/debug/ and input the URL to my article – http://www.timkainu.com/oben-tripod-review/ – it gives me a bunch of errors.

But when I turn off W3 Total Cache, everything works fine.

Here are the open graph tags in my header.php file:

<!-- the default values -->
<meta property="fb:app_id" content="170151483038653" />
<meta property="fb:admins" content="1570847387" />

<!-- if page is content page -->
<?php if (is_single()) { ?>
<meta property="og:url" content="<?php the_permalink() ?>"/>
<meta property="og:title" content="<?php single_post_title(''); ?>" />
<meta property="og:description" content="<?php echo strip_tags(get_the_excerpt($post->ID)); ?>" />
<meta property="og:type" content="w" />
<meta property="og:image" content="<?php if (function_exists('wp_get_attachment_thumb_url')) {echo wp_get_attachment_thumb_url(get_post_thumbnail_id($post->ID)); }?>" />

<!-- if page is others -->
<?php } else { ?>
<meta property="og:site_name" content="<?php bloginfo('name'); ?>" />
<meta property="og:description" content="<?php bloginfo('description'); ?>" />
<meta property="og:type" content="website" />
<meta property="og:image" content="http://www.timkainu.com/wp-content/uploads/2011/11/TimKainu_Default_Image.jpg" /> <?php } ?>

Please let me know if you need any more info and I’d be glad to supply it.

Thanks,
Tim
