These steps are similar to the ones in domain mapping. Will this over-ride what was done for the other plugin? Or does it go in a different area?
Here are the steps:
4. Upload sunrise.php to the /wp-content folder on your site – If you are using the domain mapping plugin, rename dm_sunrise.php to sunrise.php and upload it to the /wp-content folder on your site
5. Edit wp-config.php (normally located in the root of your install) and the following: define( ‘SUNRISE’, ‘on’ );
