A WordPress Multisite doamin mapping plugin
Installation -
We recommend dropping Mercator's directory into your mu-plugins directory. You may need to rename the folder from Mercator-master to mercator.
Then create a wp-content/sunrise.php file with the following:
// Default mu-plugins directory if you haven't set it defined( 'WPMU_PLUGIN_DIR' ) or define( 'WPMU_PLUGIN_DIR', WP_CONTENT_DIR . '/mu-plugins' );
require WPMU_PLUGIN_DIR . '/mercator/mercator.php';
Additionally, in order for sunrise.php to be loaded, you must add the following to your wp-config.php:
define('SUNRISE', true);
Aliases are created in the Network Admin > Sites > Edit Site screen.
