Wordpress not recieving contact form email - php

Question

I have a website I'm working on with a contact form. Simple Name, Email, and Message fields. However, I'm not receiving the email from the form; though I do get the "Message Sent" success option.
I had found a way to test wp_mail to see if that was it, using https://gist.github.com/butlerblog/5c9b805529c419b81447#file-test_wp_mail-php and that works just fine - so I have no clue what the problem is.
<?php
//loading wordpress functions
require( '../../../wp-load.php' );
define('IS_AJAX', isset($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest');
$to = get_option('admin_email'); //Enter your e-mail here.
$subject = get_theme_option(tk_theme_name.'_contact_contact_subject');
$from = $_POST['contactname'];
$name = $_POST['email'];
$message = $_POST['message'];
$headers = "From: $name <$from>\n";
$headers .= "Reply-To: $subject <$from>\n";
$return = $_POST['returnurl'];
$sitename =get_bloginfo('name');
$body = "You received e-mail from ".$from." [".$name."] "." using ".$sitename."\n\n\n".$message;
$send = wp_mail($to, $subject, $body, $headers) ;
if($send){
wp_redirect($return.'?sent=success');
}else{
wp_redirect($return.'?sent=error');
}
?>
As I said, it does hit
wp_redirect($return.'?sent=success')
so I have no clue what is wrong.
EDIT:
Did a variable dump

Warning: Cannot modify header information - headers already sent by (output started at /home/panoramicpanda/hollybrown.net/wp-content/themes/widely/sendcontact.php:21) in /home/panoramicpanda/hollybrown.net/wp-includes/pluggable.php on line 1178

The header already sent error leads me to believe output has already been started before you try and send the headers. In this case, the redirect won't work. Try this instead:
/loading wordpress functions
require( '../../../wp-load.php' );
ob_start(); // Starts data buffer.
define('IS_AJAX', isset($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest');
$to = get_option('admin_email'); //Enter your e-mail here.
$subject = get_theme_option(tk_theme_name.'_contact_contact_subject');
$from = $_POST['contactname'];
$name = $_POST['email'];
$message = $_POST['message'];
$headers = "From: $name <$from>\n";
$headers .= "Reply-To: $subject <$from>\n";
$return = $_POST['returnurl'];
$sitename =get_bloginfo('name');
$body = "You received e-mail from ".$from." [".$name."] "." using ".$sitename."\n\n\n".$message;
$send = wp_mail($to, $subject, $body, $headers) ;
ob_end_clean();// Purges data in buffer.
if($send){
wp_redirect($return.'?sent=success');
}else{
wp_redirect($return.'?sent=error');
}
Notice the ob_start and ob_end_clean. This will throw your output into the "buffer" and output it clean. The reason this is a problem, is because if any markup is sent BEFORE your sendmail (ie: html generated through templates etc, then the headers have already been started. At that point, unless your server configuration specifically allows you to modify already sent headers, then you will get the error you are getting. Using output buffering allows you to send the data as you intend.
