Mysterious XHTML Validation Error

i am trying to validate homepage of my new website and looks like i have a mysterious trouble.

If i use W3C Validator's copy-paste page source function, i only receive one warning and my page validates.

However if i use link input to validate my page it displays following 开发者_运维问答error:

A fatal error occurred when attempting to decode response body from http://www.yoursite.com/. Either we do not support the content encoding specified ("gzip"), or an error occurred while decoding it.

The error was: Can't gunzip content

My site is:

pansiyon rezervasyon portalı

Would anyone help me on this issue? Is my page valid or not?

There are a few warnings I get, such as anchors being identified by name rather than id/class, URI's being malformed (example: /desktopmodules/dnnforge - where are they/images/uovisitors.gif), and inputs using XML id syntax.

EDITED for warnings.

Result: 0 errors / 22 warnings

The problem is that the validator service does not support gzip encoded content sent by your web server. This is not quite of a problem. If your page validates with copy-pasting the source code it means that it is valid.
