I have these boxes running an early version 3.0 and I decided to upgrade to latest which I did. Compiled and working, except with one rule which spits an error (was working fine till now): acl concurrent_browsing max_user_ip -s 5 http_access deny concurrent_browsing The error: FATAL: Bungled /etc/squid/config/squid.conf line 19: acl concurrent_browsing max_user_ip -s 5 Is max_user_ip dropped or replaced or 3.4 has a bug? Thanks.
