Rails application failed to start properly?

I’m trying to do a little tutorial on creating a RoR app and i think I’m
having trouble with actually booting the server correctly. I’ve
installed Rails on my Linux server and am able to do the various
commands to get things going (such as “ruby blog” and generating
controllers. But when I tried to create an index action and check it out
on the web i got this:

Application error

Rails application failed to start properly"

When I start the server in SSH I get “Rails application started on”…which obviously isn’t right…but what/where do I
need to change?
