I decided to manually remove ISPconfig according to instructions , that is to say: rm -rfv /root/ispconfig rm -vrf /home/admispconfig (BTW It's not that the software is no good, it is just totally OTT for a person of my skill level (i.e. not a lot of experience in running a server.).). That went fine. However, it took me 12 hours to notice that the removal had killed apache2 ! urgggg. I got apache2 working again by restoring the original apache 2 config file:- cd /etc/apache2 rm -v apache2.conf cp -v apache2.conf.orig apache2.conf obviously , you'd want to check from the ispconfig install log that you have the backup file before you ...erm...remove apache2.conf ;-) if you restart apache, it will then work. I'm wondering what else is now kludged by the removal ???!!!
