pjmerrigan on "Multisite subfolder site front-end not appearing"

Hi guys

I've had a search around but can't seem to find anything relevant to this:

I have set up WordPress Multisites and now have two WP sites:

http://www.peterjmerrigan.co.uk/
and
http://www.peterjmerrigan.co.uk/spd/

The root site works as it should, but all I'm getting is a "coming soon" page on the /spd/ site (it's the standard Apache(?) welcome.php file).

I can get into the admin section of /spd/ site, create posts and pages, preview them, all fine. But for some reason they just won't show up on site. Any ideas why?

If it helps, here's my .htaccess file contents:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]
</IfModule>

# END WordPress

And the code I've added to wp-config.php:

/* Multisite */
define( 'WP_ALLOW_MULTISITE', true );
define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', false);
define('DOMAIN_CURRENT_SITE', 'www.peterjmerrigan.co.uk');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

Any help and I'll buy you a beer :)
