I published my VS 2010 asp.net application to a testing site but the WebUpload control doesn't show on a web page and get following error: The Infragistics WebUpload requires jQuery to be loaded.

I checked that Infragistics4.Web.JQuery.v13.2.dll is in the bin folder, jquery-.1.4.1, jquery-1.4.1.min and jquery-ui.min were deployed to Scripts fold of testing site same as my local machine setting. How to solve the issue?

Thanks in advance!
