Enfold Contact form not sending emails

Hello,

I’m opening a new thread as per the recommendation here:
https://kriesi.at/support/topic/enfold-contact-form-not-sending-emails-2/#post-630915

There’s seems to be an issue with the enfold theme contact form sending emails. Here’s what I have done so far:

– Installed Contact Form 7 — didn’t work
– Installed WP SMTP Plug-in and forced SMTP mail function — didn’t work
– Created a valid (Email address hidden if logged out) email, and made that default email for the wordpress website. Added the below code into the theme functions.php — Still didn’t work:

function change_cf_from() {
    return " (Email address hidden if logged out) ";
}
add_filter('avf_form_from', 'change_cf_from', 10);

– I tested php email functionality and it DOES work. I was able to test this via the below code:

<?php 
    ini_set( 'display_errors', 1 );
    error_reporting( E_ALL );
    $from = "emailtest@YOURDOMAIN";
    $to = "YOUREMAILADDRESS";
    $subject = "PHP Mail Test script";
    $message = "This is a test to check the PHP Mail functionality";
    $headers = "From:" . $from;
    mail($to,$subject,$message, $headers);
    echo "Test email sent";
?>

I’m running this theme on an AWS EC2 instance with Ubuntu:
Distributor ID: Ubuntu
Description: Ubuntu 14.04.4 LTS
Release: 14.04
Codename: trusty

I have created a wp-admin account and it’s listed in the private content.

This is a rather urgent matter, since we’re going live this week. Please, your prompt assistance is greatly appericated.

Thank you,
