Hi samh,

Pleaset create a folder under the root of your site and name it to UploaderTemp, then set the TempDirectory for the uploader control in web.config as below.

<appSettings>
    <add key="CuteWebUI.AjaxUploader.TempDirectory" value="~/UploaderTemp"/>
</appSettings>

Ensure that your site has the write/read permisson of folder UploaderTemp.

Regards,

Ken
