The line 256 shows the following function call:
$postsArray = ForumPosts::getAllPosts($topic_id, "ASC", $total_posts, 0);
and when I take a look at call.forumposts.php the function looks the following:
function getAllPosts($topic_id, $order="ASC", $perpage=0, $start=0){
nothing special with it, and no reference passing
