Dani responded to your other thread. Server issues are not always straightforward for us to troubleshoot. In your case the live server is not configured to run PHP or MySQL yet, so Dani provided some links to get you started there. Getting your server up an running is independent of the solution itself. The installation wizard helps detect some server things, but at a minimum we have to assume you have a functioning web server with PHP installed before getting to that point.
Also, it is best to stick with your original thread since it already has a place in the queue to be answered.
