Admin - Blank Page

I have installed Grav both using Grav + Admin and Garv and Admin separately and I get a blank page when I navigate to the site. I am using the most recent stable packages from GetGrav. Is anyone else experiencing this issue? My hosting is 1&1

You really need to check your php error log, or turn on php errors to see exactly what the error is. A blank white page simply means a php error of some type, but we can't help you until we know what the error is.
