AjaxFileUpload control not working on shared windows hosting

Hi,
I am using AjaxFileUpload control in my project. I am able to successfully implement and test functionality of this control on development machine. But after publishing on hosting server Ajax File Upload control stopped to work. On File upload it showing me file uploaded successfully with 100% progress but I am not able to find uploaded file on server.

Designer Code:
<pre lang="HTML">
<%@ Page Title="Add Banner – Website Content Management" Language="vb" AutoEventWireup="false" MasterPageFile="~/AdminPanel/Site.master" CodeBehind="AddBanner.aspx.vb" Inherits="Suvidhi.AddBanner" %>
<%@ Implements Interface="Idunno.AntiCsrf.ISuppressCsrfCheck" %>
