Every time a user try to access https web site they got and error about certificate not been emit by certificate authority. Removing the proxy from internet setting, i got rid of these warning. I got squid 2.16 Stable 16 with squidGuard. Tried with 3.1.0.12 and got the same thing. Anybody have this problem before, i searched this mailing list and google and didn't find any solution.
