Welcome to WebmasterWorld Guest from 184.108.40.206
The AdSense team has indeed been working hard on rolling out new features for you.
You're also right about the minor login issue. As soon as we realized it was happening, our engineers rolled back the change and we put out a blog post to explain what was happening (check out the Inside AdSense Blog for details).
If you try to log in to your account now, you'll be greeted by the traditional login page.
On a side note, we are thrilled that those of you who got a sneak peek are as excited as we are about the new page. I'm definitely passing along your praise.
However, don't get too excited about getting back in, because stats are definitely stuck right now since probably this morning (see other thread).
I'd like to be expecting a major click dump, but, considering the recent history of these "hiccups" I'm leanig toward just drawing a line through today. Really throws off your stats.
If you're still seeing the new, broken page, instead of the old page, try deleting your browser cache and/or your cookies. I just did that and the old page came back.
That's the advice I was about to give. Clear your cache and cookies and then log in again at www.google.com/adsense [google.com].
If that doesn't work, please let me know.
I just logged in using the new design, which I think looks very nice and clean, and received a warning about loading secure and nonsecure items. It looks like the login function itself is not secure, as you can't login if you don't accept the nonsecure option (the user name and password fields don't appear).
Other than that, I like the new look.
