.NET MVC Error 500 when publishing to production server

My MVC website is working perfectly on my debug machine when I press F5 in Visual Web Developper Express 2010. I've publish it a couple of time without problem but I did a lot of change lately and my latest publish didn't work as expected.

In fact, the publish works perfectly and no special message are shown. But the problem is that when I connect to the adress, I get an error 500. I google that and add the required web.config info so I get the detailed info.

Here is the information I get:

HTTP Error 500.0 - Internal Server Error

The page cannot be displayed because an internal server error has occurred.

Module: AspNetInitializationExceptionModule

Notification: BeginRequest

Handler: ExtensionlessUrlHandler-Integrated-4.0

Error Code : 0x00000000

Can anyone point me in the right direction to debug this? I can give you more information about my application if necessary!

Thanks!

Ok I found this myself with the help of the helpdesk and google.

1. Helpdesk send me to a link on how to show more error on the website.
2. Then I saw my error was "Access to the path XXXX is denied". This was related to the ClientDependency framework and was trying to access a path that doesnt exist on the server
3. I discovered on google that this path was specified in the web.config so I change the path.
4. Wasn't working more so I went on the server and changed the permission on this folder
5. It worked.

Hope this might help someone one day!
