I am runing an App on app harbor written in MVC4.

A bundle of css files doesn't work. In my local computer in debug mode I see the code of the App and I see the files. The App works as expected.

<link href="/Content/css/home/basic-jquery-slider.css" rel="stylesheet"/>
<link href="/Content/css/home/Home.css" rel="stylesheet"/>

When I upload the app to Appharbor I see the bundle in the code but the App doesn't work.

<link href="/Content/css/home?v=zhVOIpUNuvCOZhJyBcQWpMlozayor4te6k-pM29wHqI1" rel="stylesheet"/>

When I browse that link in the href I get 403 - Forbidden: Access is denied.

How to troubleshoot this?

My guess is that the path Content/css exists on disk in your app. In this case IIS would be handling the request, not MVC.

Make sure that the virtual path for the bundle (the parameter of the StyleBundle constructor) doesn't match a folder in the file system.

From the comments:

"A good convention to follow when creating bundles is to include "bundle" as a prefix in the bundle name. This will prevent a possible routing conflict."
