The character encoding of the plain text document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the file needs to be declared in the transfer protocol or file needs to use a byte order mark as an encoding signature.
Please show me add <meta http-equiv="content-type" content="text/html; charset=utf-8" />

Hi AndrewTran,
If the Telerik.Web.UI.WebResource.axd handler is not registered AsyncUpload will not function correctly and the File Browser dialogs will appear broken. Please, add the web.config settings provided in the following help article and let me know if the issue persists after that:
