Hi all, I just installed Horde groupware v3 (via a tarball) on my ISPConfig server, and it ran well. I noticed that there was a new version of the framework (4.0.5) which also brings activesync functions. So I tried to install the new version by using pear, but after the installation succeeds, Horde doesn't work anymore: It throws all kinds of errors about function from Horde that are not available anymore. Does somone know how I can successfully install a horde 4 groupware server? I did everything according to the install documentation.
