Hello Community, today I tried to update my Ispconfig 3 software via the webinterface. After a couple of minutes Ispconfig was down ... meaning the webinterface was not reachable, however, all services are started. Then I tried a manual update using the "ispconfig_update.sh" which is where I got the error Code: Notice: Undefined variable: conf in /tmp/ispconfig3_install/install/update.php on line 76 the setup has been running for 2 months smoothly and I looked into the update.php and saw that in the beginning the variable conf gets the hostname info and my hostname and hostname -f have the same output if thats important ... any thoughts how to solve this ? I have read a thread saying that uninstall.php and then running install.php might help, but does that delete the sites that were created by ispconfig? Because that would give me a ton of work, however, if there is no other way its possible too. thanks, GerminatoR //edit I have noticed my ispconfig.vhost and ispconfig.conf in /etc/apache2/sites-available are empty .. maybe thats the problem? If it is, what do I have to put in there to make it work?
