Dear Mr.Henrik Nordstrom, For the cache_effective_user, I read about that in the squid mailing list. Could you please elaborate more about this part? I think I almost try everything but not this part yet. Is it means that I need to insert these 2 lines in the squid.conf? cache_effective_user squid cache_effective_group squid Thanks again.

Usually this is caused by permission problems where your cache_effective_user do not have access to all the files needed by SquidGuard. When SquidGuard encounters a filesystem permission problem it enters silent passthru mode, allowing anything. Is there any relevant messages in cache.log? Also try testing SquidGuard manually from the command line running as your cache_effective_user (not root). Regards Henrik
