Hi! When I made my website, I clicked "Make with frontpage" because I thought it meant "set up the homepage". I don't have frontpage, nor do I know how it works and in any case, I want to make it the standard way! Does anyone know how I change it back?

Using Front Page Extensions requires non standard software to be used at the server side. If that wasn't what you wanted you will need to raise a ticket to get it undone.
