LinuxQuestions.org - Squid configuration problems

I'm using squid 3.1.4 here with CentOS 6.

I've adapted a configuration that I found in the internet. It was working, with some warnings every time I've started Squid, but working.

Now some of my blocks are not working well. The users are able to access the internet when they are not suppose to, or some websites that are also blocked. Some sites are being blocked, some not.

I've noticed as well that Squid's clock is different from the time that I have issuing "clock". 12 hours difference. Is that possible?

I'll post here my squid.conf file and the warnings that I receive to see what stupidity I've been doing.

Code:

All the time that I issue a "squid -k reconfigure" I receive the following Warnings

Code:

Working ACLs (as far as I've noticed here):

acl badsites urlpath_regex -i "/etc/squid/badsites.squid"
acl blockregexurl url_regex -i "/etc/squid/badnames.squid"
acl down_block urlpath_regex -i "/etc/squid/blockdownloads.squid"

Thanks in advance for any help.
