Hi, what exactly do I have to do?

Where I can find the sunrise.php file?

Please copy the content of sunrise.php into /home/marketop/public_html/wp-content/sunrise.php and uncomment the SUNRISE setting in the /home/marketop/public_html/wp-content/wp-config.php file.
Please uncomment the line //define( 'SUNRISE', 'on' ); in the /home/marketop/public_html/wp-config.php file.

Thank you
