This will be my third WPMU install; the other two went fairly well. So I believe I have the procedure down pat.
When I first go to my site url to start the install, everything goes smoothly. WPMU asks for the database information, I give it what it wants, it proceeds to allow me to give the weblog a title and enter my email information.
I even get the welcoming email and login information. Yet, when I click on the link in the email to login (http://mysite.com/wp-login.php), I get a Page Not Found. When I go to my site url, I'm presented with the installation screen and it wants to start all over again.
I've cleared my browser cache and everything seems to be CHMODed properly. WPMU can write to the .htaccess file, presumably, since it never once bellyached that it couldn't.
My host has Apache vhosts and wildcard DNS activated; it's a cPanel host, but as I said, I don't believe I am having problems with .htaccess as the other two installs I did use the same cPanel web host.
Thoughts?
