Hi!
I did this:
After downloading a blacklist from shallalist.de , create a target Category (call it as you want) add a least one domain and start Squidguard with the apply button (if it hasn't started yet) According to certain posts regarding to the Squidguar manual, this is a necesary condition to use blacklists and another configurations. In my particular case, I've created a target category called "White_list" on which I've added the sites contained in the default blacklist but that I wish to access anytime (for example, wikipedia.org, wikimedia.org and pfsense.org).
after doing this, I can reboot the server, an the SquidGuard service boots automatically after one minute.
Try it and, if it works for you, come back and tell us!
