I know this is a little late to the party, but about a year ago I remember reading a post saying to hold off upgrading to Ubuntu 13.10, for apache compatibility reasons. Since then, I've started new servers on 14.04 without a problem. My question is; is it now safe to upgrade ubuntu OS with ISPconfig? Thank you in advance for your time.
