 * I followed the instructions for migrating multiple blogs into WP multisite, but
   got stuck when I installed WP Domain Mapping plugin. It gives the following instructions:
 * > Please edit your wp-config.php and move the line _define( ‘SUNRISE’, ‘on’ );_
   > above the last _require\_once()_ in that file or make sure you updated sunrise.
   > php.
 * However the line _define ( ‘SUNRISE’, ‘on’ );_ is already in the config.php file–
   although there is no _require\_once()_ in the file. Sunrise.php is where it belongs,
   but I don’t know how to update it.
 * What should I do?

 * Were you using a different domain mapping plugin before? 😉
 * One or the other – not both. 😀

 * Thanks Andrea, no we haven’t used any other domain mapping plugin.

 * If there was one there, that’s why I asked. If it was the one that came with 
   the domain mapping plugin, you’re good to go.
 * Domain mapping is the only thing I know of that uses it. It doesn’t come in a
   default install.

 * The trouble is that I came into this after my client had already installed WP
   Multisite, so I’m not exactly sure what was there other than what she tells me.
   I installed WP Domain Mapping plugin, but I don’t know if sunrise.php was there
   already or not. I assume not, from what you say.
 * But I can’t configure the domains, that’s the problem. I just get the message:
 * > Please edit your wp-config.php and move the line define( ‘SUNRISE’, ‘on’ );
   > above the last require_once() in that file or make sure you updated sunrise.
   > php.
 * And, like I said… that line is there, although there is no “require_once()” in
   wp-config.php.

 * Look at the sunrise.php that she has.
    Compare it to the one in the plugin.

 * That was it! It was missing this code:
 *     ```
       if ( !defined( 'SUNRISE_LOADED' ) )
       	define( 'SUNRISE_LOADED', 1 );
       ```
   
 * Thank you!!!!
