Using phpmyadmin for almost 1 year but now log on form is not present from localhost/phpmyadmin/index.php

Image of localhost/phpmyadmin/index.php

The last time I used phpmyadmin was last week. I've been using it for over a year without any issue. I believe it's version 4.66. I went to type localhost/phpmyadmin like I always do and all I get is a "Welcome to phpMyAdmin" message but there is no place for a user name or password. Nothing has been installed or removed on the server (win2016) for months. How do resolve this? How do I prevent it? What in the world is it?
