Server Error with PHP contact form - php

Question

Not sure what is causing the error. I have tried several times but continue to get the error. Any help welcome. Thank you.
Here is my form:
<form class="form-horizontal" role="form" method="post" action="modalcontact.php">
<div class="form-group">
<div class="col-xs-8 col-xs-offset-2">
<input type="text" class="form-control" id="name" name="name" placeholder="NAME" value="">
</div>
</div>
<div class="form-group">
<div class="col-xs-8 col-xs-offset-2">
<input type="email" class="form-control" id="email" name="email" placeholder="EMAIL" value="">
</div>
</div>
<div class="form-group">
<div class="col-xs-8 col-xs-offset-2">
<textarea class="form-control" rows="4" name="message" placeholder="MESSAGE"></textarea>
</div>
</div>
<div class="form-group">
<div class="col-xs-8 col-xs-offset-2">
<input id="submit" name="submit" type="submit" value="Send" class="btn btn-primary">
</div>
</div>
<div class="form-group">
<div class="col-sm-10 col-sm-offset-2">
</div>
</div>
</form>
Here is the PHP under modalcontact.php file in my hosting server:
<?php
if (isset($_POST["submit"])) {
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
$from = 'L|D Contact Form';
$to = 'myemail#email.com';
$subject = 'Message from L|D Contact ';
$body = "From: $name\n E-Mail: $email\n Message:\n $message";
// Check if name has been entered
if (!$_POST['name']) {
$errName = 'Please enter your name';
}
// Check if email has been entered and is valid
if (!$_POST['email'] || !filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
$errEmail = 'Please enter a valid email address';
}
//Check if message has been entered
if (!$_POST['message']) {
$errMessage = 'Please enter your message';
}
// If there are no errors, send the email
if (!$errName && !$errEmail && !$errMessage) {
if (mail ($to, $subject, $body, $from)) {
echo '<div class="alert alert-success">Thank You! I will be in touch</div>';
} else {
echo '<div class="alert alert-danger">Sorry there was an error sending your message. Please try again later</div>';
}
}
}
?>

Try this code replace the from with header:
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";
$headers .= 'From: abc#gmail.com';
I tested your code and it works fine. Then what's problem on your server...
