When I tried to get my classipress site verified by McAfee I got the following response:
i... 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.
How can I fix that issue? Thanks
