Why there is not something like this:
/** * For developers: WordPress debugging mode. * * Change this to true to enable the display of notices during development. * It is strongly recommended that plugin and theme developers use WP_DEBUG * in their development environments. */ define('WP_DEBUG', false);
for allowing "MULTISITE" in wp-config.php. I think it could make turning on the "MULTISITE" more obvious.
/** * For developers: WordPress multisite mode. * * Change this to true to enable the multisite options. */ define('WP_ALLOW_MULTISITE', false);
