Have any changed been made to the comments section from version 1.2.3 to 1.5 that may affect the ability of facebook comments to post to a blog?
Using facebook comments works fine with version 1.2.3, as can below this blog post:

However, using the same code on another blog with Catch Box 1.5, facebook comments fails to post comments as can be seen here:

I have placed the facebook comments script in the header.php file of both blogs, just after the <body > tag.
I have placed the actual comment object in single.php of both blogs.
Here is where the code is place in single.php of each blog:
<div class="fb-comments" data-href="" data-num-posts="2" data-width="470">
