In common ACL I have set the target rules to whitelist the target category and set deny for everything else. Made sure to save it and apply squidguard. The trouble is it seems very inconsistent as to when it wants to block something or let something through.
As of now, it blocks pretty much everything and redirects me to the nice message I set up in squidguard. The weird thing is, even when I set everything in the common ACL to allow or whitelist, it still blocks it. I even turned off squidguard and still get the proxy denied error. It seems inconsistent to the point that I can't figure out what it is doing.

Other than that, it is working perfectly, blocking all https, and allowing only the websites I want!
One of the first websites I tested with a target category to allow was youtube. I later edited the website from youtube to something else. Even though I changed it, it seemed to still remember youtube being allowed and would let me get to it. I had to actually delete the target category that was previously youtube, and that fixed it.
Also, after marking everything allow in Common ACL to everything deny, it seems to take a reboot each time to actually take affect.
