Domain Mapping and sunrise.php issue

I am getting the following error even though I did exactly as it said and im certain i have the updated sunshine.php file:

You use old version of /home/79525-62272.cloudwaysapps.com/tttzdnxpue/public_html/wp-content/sunrise.php file. Please, replace that file with new version which is located by following path: /home/79525-62272.cloudwaysapps.com/tttzdnxpue/public_html/wp-content/plugins/domain-mapping/sunrise.php.

i've done this on another site today even, with no issues. but on this one i have this issue.
