LeMarque,
It's not any different. If you access cPanel using the server name like you just said then you won't get the error. If you or a client of yours tries to access it via a domain name hosted on your server then it will come up. It's not that big a deal you just hit ok and keep on going.
I'm about to kick the dog. It, "using the server name" works with FF but not IE7 and undoubtably a good numer of people will use IE.
So here's the question again but with an IE7 gotcha:
Do I purchase a WildCard cert for mydomain.com so that when a user tries to access cPanel via secure.domain.com they won't get a warning from IE? I've been all over the M$ IE forum and I couldn't find anyone that has a workaround for a shared SSL. I'm concerned now that even a WildCard cert won't fix the IE problem.
Just to say, my adding to my frustration, is that I can't believe I'm the only one at KH trying to fix this issue
