CSS not loading in Heroku

Question

I deployed my app to Heroku but only the assets\images are loading. The CSS files (especially the one that contains 90% of the CSS, custom.css) are not being loaded. I precompiled the assets locally and pushed them to Heroku with no luck. Only the images are loading, not the custom.css file.

I did notice an interesting error in the Heroku log:

Started GET "/users/css/parallax-slider.css" for 77.777.777.77 at 2013-06-13 02:42:09 +0000 2013-06-13T02:42:09.016864+00:00 app[web.1]: ActionController::RoutingError (No route matches [GET] "/users/css/parallax-slider.css"):

why is it looking for the css in my users controller folder? Is this why the app can't load the custom.css file?

Any help would be greatly appreciated. I've spent two sleepless nights on this and I am completely stumped.

Thanks! -b
