[Plugin: WordPress MU Domain Mapping] Broken Link

In Super Admin -> Domains, clicking on a number in the site id column takes you to a 404 not found error.

To fix it, change this line in domain_mapping.php:
$edit_url = admin_url( 'wpmu-blogs.php' );
to this:
$edit_url = admin_url( 'ms-sites.php' );
