Problems logging in ‘Page cannot be displayed’

I’ve been building a wordpress site using Xampp for localhost and now that it’s done I want to host it. So I got iPage hosting yesterday and tried the installCentral wordpress installer which was really quick and easy. I haven’t uploaded my theme yet, but when I try and log in I get to the login page and type in my username and password, and then I get:

The page cannot be displayed

The page you are looking for cannot be displayed because the page address is incorrect.

🙁

It won’t let me go to the dashboard or wp-admin without logging in again, so I’m stuck!

Has anyone encountered this problem before? And if so, how did you fix it. Thanks!
