I can not login in WP, but I can login in Gravatar.com, then make the switch to WP and that works just fine. Cookies are set correctly.
Also, reset password code does not work - gives link that does not work.
For those of you who are having login problems, try going to Gravatar.com, logging in, the on the homepage, go to bottom and click on WP - it should take you there without problem.
