[squid-users] access denied

I keep getting:

Access Denied.

Access control configuration prevents your request from being allowed
at this time. Please contact your service provider if you feel this is
incorrect.

Your cache administrator is webmaster.

I'm not sure what is wrong. I used to run squid2.7 a long while ago,
this is my first time trying to setup squid3 (squid v3.3.8 if I'm not
mistaken)

my squid.conf:
