When I upgraded my WordPress to version 2.8 every time I try to login using Firefox 3.5 I get stuck in an infinite loop.
From the login page I type in username and password, the browser changes the url to mydomain.com/wp-admin/ then back again to mydomain.com/wp-login.php?redirect_to=http%3A%2F%2Fwww.mydomain.com%2Fblog%2Fwp-admin%2F
This doesn't happen with my PC in work, just my laptop at home. From my laptop I've no such problems logging in with IE7. I've cleared everything from cookies to cache and it still makes no difference.
Can anyone help?
