Multisite 500 Internal Network Error

Hey guys,

I have been trying, for days now, to get multisite working. I have followed the instructions to the letter with no luck.

Here is what I need to update my wp-config file with:
define(‘MULTISITE’, true);
define(‘SUBDOMAIN_INSTALL’, false);
define(‘DOMAIN_CURRENT_SITE’, ‘localhost’);
define(‘PATH_CURRENT_SITE’, ‘/WordPress/’);
define(‘SITE_ID_CURRENT_SITE’, 1);
define(‘BLOG_ID_CURRENT_SITE’, 1);

I do that and WordPress is still fine.

When I update the .htaccess file with this:
RewriteEngine On
RewriteBase /WordPress/
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]

As soon as I go to log in again I get this lovely little message:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator at [email protected] to inform them of the time this error occurred, and the actions you performed just before this error.
More information about this error may be available in the server error log.

I am using WAMP and have the WordPress folder in the ‘www’ folder under ‘WordPress’.

Any help on resolving this would be spectacular.

Cheers
