Thanks. IT says "UploadModule not installed into web.config."
As far as I know the dll is copied over as is the license file and the web.config is updated to include the following lines:
<appSettings>
<!-- AjaxUploader Settings -->
<add key="AjaxUploaderLicense" value="~/Resource/Licenses/AjaxUploader.lic" />
<add key="CuteWebUI.AjaxUploader.UploadSpeedKB" value="100" />
and
<system.webServer>
<modules>
<add name="CuteWebUI.UploadModule" type="CuteWebUI.UploadModule,CuteWebUI.AjaxUploader"/>
What have I left out?
