Redirect Loop error on home page

I have an issue that my homepage is not loading giving me a redirect error.
This happened when I installed aide user registration and then uninstalled it.

The site is http://www.hairserenity.com.au
The error is here:

The page isn’t redirecting properly

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

This problem can sometimes be caused by disabling or refusing to accept cookies.

Any help would be appreciated.
Cheers
