WordPress MU

I have installed the multi-site plugin on WPMU. I can log in as administrator on the primary blog when using Firefox. However, when I try to logon to a different blog as the administrator, I can't get into the site.

The URL that is displayed after the attempted login is:

http://wrstarling.com/wp-login.php?redirect_to=http%3A%2F%2Fwrstarling.com%2Fwp-admin%2F

Now the interesting part. I can login to the second blog as either administrator or authorized user using Google Chrome. I do have login issues using Internet Explorer as well.

I have tried clearing the cache and cookies in both Firefox and IE. Have even rebooted the machine. No luck with Firefox or IE.

Jerry,
After some search on the subject, I found your post and... I have the exact same issue.
I get the same url on both Firefox and IE as you, but no problem with Google Chrome.

Have you managed to solve this?

Try adding the admin account as a member of the mapped site.
