When I use the McAfee Site Advisor site verifications sytem, I get the following messages:
It appears that the Web site domain.com (or domain.com) is returning an HTTP 2xx or 3xx status response code in the header of 404 pages.
We cannot verify a Web site that is configured this way because it allows anyone to verify themselves as the owner of your site. Please update your Web site server configuration to return 404 status codes in the headers for pages that do not exist. Once your site is configured this way then you can return and request a file name verification.
I don't know what to do and how to resolve this error. My website is build using the Magento platform.
