Hi Till, Thank you for your reply I try this commands: ln -s /usr/local/ispconfig/interface/web /var/www/ispconfig ln -s /usr/local/ispconfig/interface/web/index.php /var/www/ispconfig but the message: "Forbidden You don't have permission to access / on this server." still appear.
The second command is wrong, please undo that. Just run the command that I posted. Then check that apache mod_fcgi is installed and activated.
