[Plugin: WP Super Cache] Post listing outside of WordPress install not working

Hi everyone,

I recently install WP Super Cache and got it set up and running perfectly, except for 1 part. On the Home Page of my site I have PHP retrieving the 5 latest posts, it works well when Super Cache is off, but when it’s on it returns a bunch of random characters and breaks the whole page.

Home Page code

<?php
						require('blog/wp-load.php');
						query_posts('showposts=5'); ?>
					<ul>
						<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
						<li><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></li>
						<?php endwhile; else: echo "No posts... yet"; endif; ?>
					</ul>
					<?php wp_reset_query(); ?>

I have tried the following lines in “Accepted Filenames & Rejected URIs” (this is based off a post I found after some Googling)

wp-.*\.php
index\.php
^/$
/$
^example.com/$
^example.com$

Any help would is greatly appreciated.

Thanks
