I (and a friend on a similar server)
got HTTP ERROR
on Wordpress image upload on new Ubuntu 12.04 server at Hetzner ubuntu 12.04 minimal. I guess this has something to do with wrong setup or something.
At "The Perfect Server - Ubuntu 12.04 LTS (Apache2, BIND, Dovecot, ISPConfig 3) - Page 4"
I had to PURGE before INSTALL at "apt-get install postfix postfix-mysql postfix-doc mysql-client mysql-server openssl getmail4 rkhunter binutils dovecot-imapd dovecot-pop3d dovecot-mysql dovecot-sieve sudo
" - otherwise the "General type of mail configuration: <-- Internet Site
" do not show up and postfix never worked otherwise.
Could this be the reason for the HTTP ERROR ?
Would be nice with a "The Perfect Server @ Hetzner"
