Your Page should not contain the following portion of HTML as these are already contained in the MasterPage:

XML

<html>

<head>
</head>

<body>
...
...
</body>

</html>

Most likely this is the problem. So, remove these form the Page.

Your content page should only contain the JavaScript and the following code:

XML

<script runat="server">
     Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Session("ProductName") = LinkButton1.Text
        LinkButton1.Attributes.Add("onclick", "window.open('promo.aspx',null,'height=360, width=420,status= no, resizable= no, scrollbars=no, toolbar=no,location=no,menubar=no ');")
        Session("ProductName") = LinkButton2.Text
        LinkButton2.Attributes.Add("onclick", "window.open('promo.aspx',null,'height=360, width=420,status= no, resizable= no, scrollbars=no, toolbar=no,location=no,menubar=no ');")
    End Sub
   </script>

<asp:Content ID="Content1" ContentPlaceHolderID="Main" Runat="Server">
    <asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton_Click">Change Password </asp:LinkButton>
    <asp:LinkButton ID="LinkButton2" runat="server">Upload CV</asp:LinkButton>
</asp:Content>
