System.NullReferenceException at Umbraco.Web.Mvc.ControllerExtensions.RenderViewResultAsString
Hi, I'm facing this intermittent issue that Umbraco 7 suddenly crashes and throws NullRefrenceException on RenderViewResultAsString method. This error got resolved when I redeploy the site or install an empty Umbraco Package.
My deployment is on Azure stack trace below, has anyone faced similar issue? :
System.NullReferenceException: Object reference not set to an instance of an object.
