I need a contact submit form fixed - php

Question

Ok so I have the modal toggling, that is easy with bootstrap. But now, whenever I click submit the form gets redirected to php/contact-process.php. It looks like the php is processed but then just stays at a white screen, and not being redirected and no email is received to my main email(i put example#gmail.com for stackexchange question). Please help me.
