SUNRISE.PHP No Content in File & Not in wp-config.php

I have an error message that I noticed in my Multi-Domain Settings after a test domain did not add properly. It says to copy the contents of sunrise.php in the wp-content file location and uncomment wp-config. Well, sunrise.php shows in the wp-content file location, BUT there is nothing in it, and there is not any reference to SUNRISE in the wp-config file. I need help understanding how to fix this so multisite function will work properly. Thanks
