No allowed http site

[sasab]

Hi,
I have installed pfSense latest version and squid & squidguard but I have a strange problem (both use squid in transparent mode is not the transparent mode) the problem is that all http web sites are blocked instead is ok to access https websites !

I configured the "proxy interfaces" in LAN and "transparent proxy interfaces" in LAN, I also tried plugging in the "Allowed Subnet" my internal subnet, the result is always the same.
to every request I have the message:
Request denied by pfSense proxy: 403 Forbidden

I can not understand what I'm wrong :-(
Thanks.

I resolved, the problem was that he had in squidguard configuration about default !all
thanks.
