I did try the deletion of any folders that said 'support' Then I waited a while to let the server clear it out. Then I went back on and created the subdomain again. It creates it fine. I just can't access it. Even if I load up a test page, I cannot display anything that is in:
http://support.mydomain.com
I get an error saying it does not exist. Oddly enough I did other subdomains and accessed them without any trouble. I put a prefix onto the word support like this:
http://prefix-support.mydomain.com
It works fine and I can access it. So, it must be something about the word support. HMMMM
