revive login and panel appears different

[fishin]

I'm trying t figure out why my login page doesn't display properly like the following in this page: https://www.revive-adserver.com/blog/portfolio-item/login-screen/

Just shows like this:

"Revive Adserver

Authentication
 
      Welcome to Revive Adserver
Enter your username and password to log in
     
Username:     
Password:     
     

Forgot your password?"

How do i get it to show the other way as in the link i sent
