wordpress multisite subdomains

I'm having trouble installing the wordpress multi-site subdomains
http://uploadsale.com/ that is fine
now when I create http://site.uploadsale.com/ I receive this error I created the wildcard dns Im using bluehost and they allow the wildcard dns
this is the error I get
Index of /

Apache/2.2.27 (Unix) mod_ssl/2.2.27 OpenSSL/1.0.1e-fips DAV/2 mod_bwlimited/1.4 Server at site.uploadsale.com Port 80

Do you have any idea what is going on, thank you
