I just managed to solve this by increasing the priority from 5 to 20. Any ideas why this would be the case? the_title(), the_categories etc work fine.

//Lets add Open Graph Meta Info
function insert_fb_in_head() {
	global $post;
	if ( !is_singular()) //if it is not a post or a page
		return;
	echo '<meta property="og:description" content="' .get_the_excerpt($post->ID). '"/>';
}
add_action( 'wp_head', 'insert_fb_in_head', 5 );

I should have said, I’ve tried with both get_the_excerpt($post->ID) and get_the_excerpt()

Well, after a little bit of playing, I managed to half fix this by changing the posts per page in the Reading pane of the dashboard. I set it to 4 and it fixes things.

My guess is that the is_404 is not set against my updated ‘posts per page’ in my query. Interesting stuff.

Anyhow, I’ve set the Reading pane back to 10 so if anyone wants to see this behaviour in action then visit the links above. Once I make my site live, I’ll have to set it back to 4.

Having read the link provided by esmi, I’m fairly certain it will do what I need.

Many thanks.

To top it all off, I’ve just noticed that using
query_posts( $query_string.'posts_per_page=3' );
doesn’t limit it to 3 posts – it limits it to 3 posts + stickies. I’m going to be having nightmares about them tonight!
