If you need to test a static site before you get a domain name, this feature is broken. Please fix!!!
to access the feature:
cPanel > domains > preview website
For those who aren't familiar with this URL, "previewmywebsitenow.com" is owned by GoDaddy.
Yes, just had same problem. I did a search on Google and the site seems to be leaking all sorts of files to Google's search engine, like here: www.previewmywebsitenow.com/exim.conf
Doesn't instill confidence in their service!.
