Domain Mapping sunrise.php "old version" msg

Hey there!

I have just installed the domain mapping.

the plugin asked to copy the sunrise.php to the wp-content folder so i did.

(and also to add the define('SUNRISE', 'on':wink:; in the wp-config file )

After that i refresh the plugin i get the massage:

"You use old version of /home/sites/ file. Please, replace that file with new version which is located by following path: /home/sites/"

Why is it the old version? i just added the plugin.

Please Help!
