I am using multi domains and domain mapping. I am recieving the following error even though sunrise is defined in wp-config and the file was dynamically updated.

Please copy the sunrise.php to /home/sofia/Projects/propertystork.co.uk/wp/wp-content/sunrise.php and uncomment the SUNRISE setting in the /home/sofia/Projects/propertystork.co.uk/wp/wp-config.php file.
