Fix Pi-Hole blank white screen on admin

fix pi-hole.md

1. Open a terminal session on the PI
2. To enable the server to handle php scripts the fastcgi-php module should be enabled by issuing in the command

sudo lighttpd-enable-mod fastcgi-php

# Then reload the server using
sudo service lighttpd force-reload

Then go back and check the admin page.

If there is still and issue, make sure you have PHP running. Create a simple PHP script and load it in www directory.
