主题：Fatal error for function: get_post_format () (15 posts)

I just installed WordPress using Dreamhost one-click advanced install.

I deleted my example comment, but my example post is still published.

When I load my site:

http://www.clicktruemedia.com/

I get this error message:

Fatal error: Call to undefined function get_post_format() in [...]wp-content/themes/twentyten/loop.php on line 60

Here's line 60 of loop.php:

<?php if ( in_category( _x( 'gallery', 'gallery category slug', 'twentyten' ) ) || 'gallery' == get_post_format( $post->ID ) ) : ?>
