Why am I unable to login after converting to www?

Question

So I originally designed the site without the www. I've since realized that it's going to cause more problems than necessary.

I created a rewrite rule that converts to www.

I then changed the domain in wp-config

define( 'DOMAIN_CURRENT_SITE', 'openeye.net' );
define( 'PATH_CURRENT_SITE', '/' );
define( 'SITE_ID_CURRENT_SITE', 1 );
define( 'BLOG_ID_CURRENT_SITE', 1 );
define('WP_HOME','http://www.openeye.net');
define('WP_SITEURL','http://www.openeye.net');
define('WP_MEMORY_LIMIT', '96M');

I'm now not able to edit pages or access wp-admin. What would cause that?
