Creating a fresh Wordpress MU 2.6.1 install and running into problems when I first try to login.
The installation itself seemed to go OK and when I browse to my main page I get the stock "This is a WordPress Mu powered site" page with links to Log in, create a new blog, etc.
Problem, though, is that when I try to actually Log in, I just end up in a continuous loop.
I click that link and end up at http://anibee/wp-login.php. When I enter my authentication info and hit Log in, though, I'm redirected back to:
http://anibee/wp-login.php?redirect_to=http%3A%2F%2Fanibee%2Fwp-admin%2F
Login again, and returned to the same http://anibee/wp-login.php?redirect_to=http%3A%2F%2Fanibee%2Fwp-admin%2F page.
I noticed that no cookies are being set, either, when I try to login. And I don't see any errors in my access or error logs.
I also just dropped and recreated my database, and deleted and replaced all the WP Mu files. Still the same problem.
