404 Error for MP even with http Handler added to web.config

[dgreenuk]

I removed the validate attribute from the web.config handler and got this message:

System.Web.Routing.UrlRoutingModule does not implement IHttpHandlerFactory or IHttpHandler

So i googled and tried changing UrlRoutingModule to UrlRoutingHandler

The IHttpHandler error went away but back came the includes.js 404!
