No idea how you have your server set up, but according to this page, seems like there is something wrong with how PHP is set up

Alternatively, it also seems like you’re hosting on Windows? Is that WAMP? I know a lot of people use that with Wordpress and Roots without issue, but it could possibly be an error in the .htaccess

Thank you for the reply . I am using XAMPP new version for windows 8 . It only got error when i used the root themes.

Disable support for the rewrites in lib/config.php and try again. If that fixes it, it’s most likely that you don’t have mod_rewrite correctly enabled in XAMPP’s httpd.conf.
