amweissMy main site is working fine and I can log in to administer it, but when I (or someone else) starts up another blog, it's impossible to log in to administer that blog because you can't get past the login screen (at http://www.example.com/testblog/wp-login.php) because it always says the username field is empty - no matter if the credentials you put in are correct. I've deactivated any plugins that might be the problem, but that hasn't helped.
Any advice on how to fix this?
Thanks
