I have a HTML file, which I want to validate. The doc type I used is <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> I'm getting the following message when my page is uploaded. Sorry, I am unable to validate this document because its content type is text/plain, which is not currently supported by this service. The Content-Type field is sent by your web server (or web browser if you use the file upload interface) and depends on its configuration. Commonly, web servers will have a mapping of filename extensions (such as ".html") to MIME Content-Type values (such as text/html). <b> can you pls help me. </b>
(I am not sure it's such a good idea to use the bug database for such calls for help. The mailing-list would be a better choice, perhaps) Did you, by any chance, use the "file upload" interface from a computer running windows XP (SP2)? If so, check http://www.w3.org/QA/2005/01/Validator-IE_WinXP_SP2
This isn't a bug in the Validator. This situation is normally caused by a misconfigured web server, a similarly misconfigured web browser, or the bug in the version of Internet Explorer distributed with Windows XP Service Pack 2 mentioned in Comment #1. Closing as Invalid.
