That's a good question. I'm not sure what is the answer. I'll do some research in Google and get back to you if I got an useful answer. You should email the people at iPage as they probably could assist you..
I think that if you have a pop-up blocker you may not see the notification about the new interface..
The new interface looks good at first glance. I have never liked the cluttered old interface. If they could stop bombarding you with silly ads it would be nice.
But now I can't get in, it says the certificate has been revoked by issuer..
My interface didn't update until today..
At first I thought "Oh, they've changed it, why?", just because I was used to it before and a little resistant to change..
Then I decided I didn't like it before or after so remain pretty indifferent...
Seems that my account just got updated... looks alright. I wanted to give it a try... but I havent got anythign that needs doing!..
