Hi, I have had the following problem twice now. The first time I assumed it was because I installed webmin on top of ISPconfig but this time I have kept the install clean and not tried webmin. I was logged in through ssh and restarted apache2: Code: [email protected] I followed the Perfect Server on Ubuntu howto exactly. Please note I have solved this solution. Using advice from https://bugs.launchpad.net/ubuntu/ source/libxml2/ bug/151045 (i.e I removed /usr/local/lib/libz* and restarted apache2) but I was interested to know what the issue was.
