Forum: Typo Typo, shared hosting, and a subdomain....

I need some help with my Typo application. I moved it up to my host,
setup the htaccess and redirects all that fun stuff. The redirects and
htaccess seem to be good, but I get the wonderful, "Rails application
failed to start". In my error logs I get this,

Can anyone help me figure out the issue? I am new rails and lost on what
is causing this to fail so miserably. Thanks.
