Hello,

I have a page with a basic modal popup. The code is as follows:
Code:
<%@ Page Title="" Language="VB" MasterPageFile="~/re.master" AutoEventWireup="false" CodeFile="addproperty.aspx.vb" Inherits="Register_default" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
    <title>Admin - Add Property</title>
    <style>
    .modalBackground{
        background-color:black;
        filter:alpha(opacity=90) !important;
        opacity:0.6 !important;
        z-index:20;
    }
    .modalpopup{
        padding:30px 10px 30px 10px;
        position:relative;
        width:550px;
        height:100px;
        background-color:white;
        border:1px solid black;
    }
    </style>

This code had been working fine for months, however, I recently moved the site to a new host and now the modal popup appears at the bottom of the page. See below:

The new host claims they support AJAX and have verified for me that AJAX is "enabled" on the server, but clearly there's something different between the 2 hosts? When I transferred my site, they did force me to comment out a number of lines in the web.config file. The web.config now looks like the following:

Any help you can provide as to why AJAX is not working is greatly appreciated!
