Where can I find the latest version of sunrise.php?

Hi there,

I am trying to set up Domain Mapping, but I have a message on top of the admin panel saying

'You use old version of /home/rypinzpg/public_html_salgshub/wp-content/sunrise.php file. Please, replace that file with new version which is located by following path: /home/rypinzpg/public_html_salgshub/wp-content/plugins/domain-mapping/sunrise.php.'

I deleted the file, and activated the plugin again - with the same result. The file was copied, but still the same message.. The version of the installed plugin is 4.1.1 and the sunrise.php now is 1.0.1.
