Multisite migration ( pages 404 )

Hi All,

I moved a multisite installation from one server to another, and using PMA and Safe Search Replace i changed (almost) all the old url’s for the new one.

I can log in to the back-end of my multisite and look at the pages etc – all under the new url – but when i click to view the page i get a 404.

??

Any ideas why this might be happening?

my htaccess file looks like this:

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

# uploaded files
RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [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).*) $1 [L]
RewriteRule  ^[_0-9a-zA-Z-]+/(.*\.php)$ $1 [L]
RewriteRule . index.php [L]
</IfModule>

# END WordPress

Any ideas would be great – thanks!!
