Make sure that you are uploading to the public_html or www folder. Only the files placed within these folders will be viewable by the public. If you are sure that you've uploaded your files to the correct location and your site still continues to not work it's very likely that your DNS is not set up properly.
For your domain to work with our services it will need to be pointed at the following nameservers:
ns1.sunserver.in, ns2.sunserver.in
