Hi,

Do you have a live URL so I can do a test ?

If your IIS is using intergrated mode , you need to add such configuration to system.webServer node :

      <system.webServer>

            <validation validateIntegratedModeConfiguration="false"/>

            <modules runAllManagedModulesForAllRequests="true">

                  <add name="UploadModule" type="CuteWebUI.UploadModule,CuteWebUI.AjaxUploader"/>

            </modules>

      </system.webServer>

Regards.
Terry
