Web page not coming up
I'm a real newbie to ISPConfig, so take this with a grain of salt.
Are you certain that you're replacing the correct index.html? If your install is similar to mine, you would expect to find it in /<base dir>/web<some digits>/web. In the case of my system, I've been doing a lot of testing, therefor a lot of inserts/deletes, and have a lot of directories under <base dir>. I find it quite easy to replace the wrong index.html file.
