Domain Mapping Issue on a Recently Migrated WP Network

Getting an error when trying to access the domain mapping settings, at first, the issue was that it was not possible to map the domain but I was able to see the domain mapping settings.

This network was migrated recently, here's the error on the Domain Mapping page Please edit your /home/bwsdrinks/public_html/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.

The sunrise file is on wp-content and it's defined in the wp-config.

Support access is enabled and the information is included in the lc chat.
