php脚本离线工作但不能在线工作

Question

LIVE SAMPLE this is my sample live website

The Problem is my code for a "Contact-Us" works fine when i use it offline(wampserver) but when i upload it to my cpanel it doesnt work... i tried almost everything but the alert just sends me the "connection failed" the Connection.php works fine i can connect to the database, the problem seems to be in the INSERT statement. i don't see any problems in my code, because my other "registration" form works just fine online see my sample website. there's no error problem on my code because i already cheked the error log:

    <?php 

include_once 'Connection.php';

if(isset($_POST['btn-index']))
{
 $first_name = $_POST['first_name'];
 $email = $_POST['email'];
 $contact = $_POST['contact'];
 $subject = $_POST['subject'];
 $message = $_POST['workarea'];


$first_name = stripslashes($_REQUEST['first_name']);
$first_name = mysqli_real_escape_string($conn,$first_name);

$email = stripslashes($_REQUEST['email']);
$email = mysqli_real_escape_string($conn,$email);

$contact = stripslashes($_REQUEST['contact']);
$contact = mysqli_real_escape_string($conn,$contact);

$subject = stripslashes($_REQUEST['subject']);

$message = stripslashes($_REQUEST['workarea']);
$message = mysqli_real_escape_string($conn,$message);

$sql = "INSERT INTO `inquiry` (First_Name,Email,Contact,Subj,Message)
VALUES('$first_name','$email','$contact','$subject','$message')";

if($conn->query($sql) === TRUE)
        {
