I have tried to upload .htaccess file to the root directory of domain to install script but it shows error. I looked in log and saw following: .htaccess not allowed. I tried to modify apache configuration but it doesn't accept rewrite feature. maybe it's becose of apache 1.3 ? By the way here is the log text: /var/www/web7/web/.htaccess: Options not allowed here
You must change the allow override options for the /var/www/*/web directories. They are defined at the end of your apache / apache2 or httpd.conf file, in the part that was added by ISPConfig.
