    Hi @Joris

    Welcome to the forums, glad to have you aboard!

    Have you ensured that the sunrise.php file has been correctly moved to your /wp-content/ folder?

    Also, please ensure that the following line has been correctly added to your wp-config.php just above where it says "That's all,stop editing":

    define( 'SUNRISE', 'on' );

    Finally, if you are allowing your site admins to map multiple domains to their sites, please ensure that the following is also added to wp-config.php just before the above:

    define( 'DOMAINMAPPING_ALLOWMULTI', 1 );

Thank NAME, for their help.

Let NAME know exactly why they deserved these points.
