Dear all

I’m newbie to unicorn server.  
recently I got a problem when I was trying to run unicorn in production  
model.  
like command `unicorn -E production`. then I lost all my css styles in  
the browser.  
But everything works fine when I just type `unicorn`

when unicorn running in the production environment, I was trying to  
access my css file in the browser by the url  
‘[http://127.0.0.1:8080/stylesheets/scaffold.css](http://127.0.0.1:8080/stylesheets/scaffold.css)’, I got 'No route  
matches “/stylesheets/scaffold.css”  
but it worked fine when unicorn running in the development environment.

Please help me, it’ll be very appreciated.

Best Regards,  
Lewis
