Hi,
Please try the last version.
If you want to make sure the uploader have no script cache, you can use the
uploader.ScriptSource=MvcUploaderScriptSource.EmbedCode;
or
uploader.ScriptSource=MvcUploaderScriptSource.None;
and you need reference the <script src='CuteWebUI_Uploader_Resource.axd?type=script&_ver=1234'></script> in your page.
Regards,
Terry
