The Uploader demo page on the demo portal (the actual portal page, not the Uploader demo itself) includes a link to the Uploader's ReadMe file. The link specifies the filename is all lowercase ("readme.txt") while the actual file name is camel-case ("ReadMe.txt") so the link breaks. The file is present on the server, the link just doesn't work. (Note that it works fine when I test on my local machine).

The change would be required in demos/uploader/demo.html
