Hi, I''m hoping someone can help me with my setup. I''ve installed ruby (1.8.2), gems (0.8.10), and rails (whatever was current as of about two days ago). I''ve got an app (been trying the Todo tutorial) setup under a virtual host as a subdomain (httpd.conf is setup according to directions in http://wiki.rubyonrails.com/rails/show/HowToCreateVirtualHostsForRailsAppllications ). When I go to my subdomain.domain.com, I get the "congratulations" page. Chmod everything to 755. Check that I''ve got all the cgi, mod_rewrite stuff the congrats page says to have in my httpd.conf. Great. But..... When I try to access a controller at subdomain.domain.com/todo, I get "Application error Rails application failed to start properly." And the Apache error log says: "Premature end of script headers: /home/heragrou/public_html/Tickets/public/dispatch.cgi" Having searched the web on this, it looks like this is usually due to problems with either permissions, shebang lines, or Windows line endings. But... My file is chmod 755, the shebang line checks out (as far as I can tell), and I''m running Linux, so no Windows line endings here. I''m starting to think this may have something to do with FastCGI (I don''t think it''s installed), but I''m just grasping at straws here. Any help would be greatly appreciated. I''m really anxious to get started with Rails. Thanks, Alison Rowland
