Google Sitemap not verifying - error 200 ?

hi,

I have submitted my google sitemap and it asked me to upload the file which I created in public_html folder. Now when I tried to verify it, it gave me error,

Verification status: NOT VERIFIED
We've detected that your 404 (file not found) error page returns a status of 200 in the header.

This is the first time, I have faced this problem and I am not sure what is the problem. Can anyone help me

 

What G is saying is that they requested a file known not to exist on your machine, and your server returned a HTTP Status code of 200 OK -- meaning it found it. So say they requested:
http://www.your-site.com/this-aint-there-912AHD81ja88A
Your site returned content for that page, along with an 200 OK.

It's alright to return content, but the status the server returns should be:
HTTP/1.1 400 Not Found

If your running Apache, there is an ErrorDocument directive that you can point to a page to send when pages aren't found, and send the correct status.

I checked the two sites in your sig, and they both return the proper 404 Not Found.

try to verify with meta tag method.
