How to fix wordpress on Nginx 404 not found page

Please add following text into nginx configuration file.

location / {
                # This is cool because no php is touched for static content.
                # include the "?$args" part so non-default permalinks doesn't break when using query string
                try_files $uri $uri/ /index.php?$is_args$args =404;
    }


    if (!-e $request_filename) {
            rewrite ^.*$ /index.php last;
    }
