I've been doing some research on this since it has happened a few times.
I think it may be related to the configure.php file.
In the configure.php file, do you have the site listed as http://domainname.com, or http://www.domainname.com?
In any case, change it to be the other way.
So if it's
http://www.
make it
http:// instead,
or the other way around would be "
http://domainname.com
make it
http://www.domainname.com
Let me know if that works.
Then if that works, go to http://www.dnsstuff.com/ and lookup your domain name. You my have some dns errors associated with your domain name.
