I'm using Debian 3.1 and ISPConfig 2.2.18. After upgrading to Debian 4.0, do I have to reinstall ISPConfig?
No, you dont have to reinstall ISPConfig. But you should compare your configuration with the perfect setup for debian etch, as some config file directive has been changed. If I remember correctly, thats especially for SASL the case.
Again and again. Now Apache starts up, but all ispconfig sites are gone. They all show 'It works'. Well, it doesn't. I'll start from scratch now I have only a few sites on it.
