2. I believe it works best when your setting up a site to put in the hostname field the firstpart of your domain ie: eron Then where it asks you for your domain name put in hobby-site.com
This is what worked for me and its probably not a complete answer but I hope it helps.
I had already done that jeskimo5 but I still get the same shared IP page after having loaded a single index.html page via ISPConfig's FTP page.
