Aranworld on "get_col returning empty result on remote server"

You know it seems like something has been disabled in my WordPress installation, because when I do this:

global $wpdb;
 $result=$wpdb->query( "SELECT * FROM wp_posts LIMIT 1"
			     );
 echo $wpdb->func_call;

On my local server I see this expecte result:

$db->query("SELECT * FROM wp_posts LIMIT 1")

On my remote server absolutely nothing gets echoed to the screen.
