Atletica Contact form blank page

Trying out Atletica Theme and setting up the contact form at http://writecraftwordpress.com/score/contact-form-test/ all I get is a blank page. It's a multisite WP network I run. I would buy this theme if it will work. Is there some multisite trick to get it to work?

Hi!
Oh, no. It is not a trick. Could you send us the code of the file feedback.php?
