HTTP problem with squid after upgrading to version 2.3

[nottyboy]

Hi all,

I upgraded my pfsense from 2.1 to 2.3 today, after starting squid proxy, internet access gone haywire, all http traffic is being directed to https when it is not https, after I disabled squid then it will be back to normal, I was using squid not squid 3 previously on version 2.1, squid 3 is totally new for me, is there any setting setting that I missed out?

Thanks!  :'(
