Dear Falko, I wonder how I could permanently 'fix' this
setting in Vhosts_ispconfig.conf?
I change it there for one of the websites from AllowOverride None to AllowOverride All, and everything starts to work, but some time later the setting reverts back to AllowOverride None
Also, I can't reset the setting globally.
if I put AllowOverride All inside <Directory /var/www/*/web> in /etc/apache2/apache2.conf, nothing seems to happen.
I have ISPConfig 2.2.25, "perfect setup", Debian Etch.
