Multi Site and Domain Mapping – Can't log back into WordPress



I’m new to Multi Site and domain mapping and I’ve encountered a strange problem. I got everything working but with this one major issue.

I’ve added the sunrise code [define(‘SUNRISE’, ‘on’:wink:;] to wp-config.php, however when I log out of wordpress and try to log back in I go nowhere except back to the login screen. The only way I can get back to the dashboard of My Sites is to go to the wp-config.php and delete the sunrise line. Then I can login but of course the Domain Mapping no longer works.

Looking forward to your help.
