I'm trying to get my contact page to work so when you fill out the contact form it lets the user know that the email was sent without having to hit the back button to go back to the page. I've followed the steps in the "Contact Form" section and when I copy and paste the information and test it out all I get is:

{"message":"Email successfully sent!","code":1}

I only get this messafge when I use the last php code. If I use the php code before that then I get a "Email sent!" message. According to the website the page is suppose to automatically reload once the user clicks submit. The user shouldn't have to click the back button to get back to the page. Any help would be greatly appreciated!
