Rails and a development domain

I'm trying to use http://ls1.bigseapreview.com as a domain for a Rails project. The problem is it doesn't seem to be correctly mapping any routing apart 开发者_StackOverflow社区from the home page.

I have added /about but you can see that you will just get a 404, but it works locally.

What do I have to do to fix this?

Can you add your routing file? +I added /about and it looks like it's working

Are you sure that this is a Rails project? Your "about" link points to "/about.php".
