Re: [webmin-devel] &backquote_logged

An environment variable definately could be the cause..
You can see variables that are set by miniserv by looking at the env_ 
lines in /etc/webmin/miniserv.conf , and you may want to try adding 
some of those that you have set at the command line.

Also, I presume that when you run squidguard manually it is as root? 
The program might be failing when webmin runs it as root for some 
reason ..
