Hey guys,

I am trying to alter a Wordpress blog page. I want it to display 4 of the latest posts only but I am not sure what to amend.

Currently it displays all the posts, two per line. Can anyone help please?

This is the blog code

PHP Code:
<?php
function theme_shortcode_blog($atts$content null$code) {
    global 
$wp_filter;
