Hey, I tried SilverStripe a while ago and I think you were between versions 1 and 2. The documentation was for old version of SS and I had some trouble. This time is far better but I am having a little trouble with tutorial 1.
I have added the HomePage page type to the site/code folder. I have then done the admin dev flush thing. A new page option appears called 'Home Page'. This differ's slightly from the option 'HomePage' which appears in the tutorial. When I add the HomePage.ss template into the tutorials folder and refresh the page nothing happens. I had added ?flush=1 but still no joy. I check the source and it is definately showing the Home.ss template file.
