This could help!
After bying a certificate at Go Daddy, i installed it on my apache unix server.
The certificate installation was ok everywhere, firefox, Chrome, IE9, Opera, Iphone, IPad, Android.
Except on IE8 and in the Go Daddy test tools, where a get an error message.
I solved this problem, simply (after hours!) by changing the next parameters in my apache configuration file.
In the default SSL virtual Host section.
I understand that some browser like IE8, QtWeb, when reaching a https web site ask then the certificate whitout the new HTTP host parameter. Then they get the values of the default virtualHost .
