Site crashes when starting RSS

When I add this to .htaccess the only thing I get is: No input file specified. Sit e is dead.

File attr. is set to 644.

Your wp-config.php has to be edited, but is not writable. Set your wp-config.php to writable and reload this page. To safely enable SSL on your server configuration, you should add the following line of code to your wp-config.php.
//Begin Really Simple SSL Server variable fix
?? $_SERVER["HTTPS"] = "on";
//END Really Simple SSL

The page I need help with: [log in to see the link]
