Here's the scoop. I created an Umbraco 6 MVC app locally (pointing to a Yocto shared SQL server appharbor add-on), installed it and it runs fine. I can add doc types, create content, blah, blah.... locally.
Then I pushed the solution to the AppHarbor GIT repo and it built and deployed successfully. However, to my surprise, I get a lovely YSOD and the following error when I try to go to the home page:
[NullReferenceException: Object reference not set to an instance of an object.] Umbraco.Web.UmbracoModule.BeginRequest(HttpContextBase httpContext) +13 Umbraco.Web.UmbracoModule.b__5(Object sender, EventArgs e) +253
System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +136 System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +69
The app's errors logs report this error is occurring for the following request paths: / /favicon.ico
This one has me stumped. Any thoughts?
