few remarks - the install script gave me errors on "cp /root/lsws-2.1.11/docs/*.gif /the/destination/dir/for/lshttpd"
the errors were also for the admin* content.
so when i Upgrade with the 2.1.11 the admin panel wasn`t working.
so i again Upgraded but with 2.1.10 and then only linked lshttpd->lshttpd-2.1.11 from the package
my mistake: i already have downloaded the freebsd6 version when i asked the question but error was the same. so when i read your post i deleted the previous lsws-2.1.11 dir and donwloaded again ....
