I upgraded Orion form 7.8.5 to 8.5 today. Ever since, when I try to login to the website, I get the following error.
Orion Website Error
An error has occurred with the Orion website.
Additional Information
System.NullReferenceException: Object reference not set to an instance of an object. at ASP.orion_netperfmon_nodedetails_aspx.__BuildControl__control2() at ASP.orion_netperfmon_nodedetails_aspx.__BuildControlContent3(Control __ctrl) at System.Web.UI.CompiledTemplateBuilder.InstantiateIn(Control container) at ASP.orion_masterpage_master.__BuildControlContentPlaceHolder1() at ASP.orion_masterpage_master.__BuildControlaspnetForm() at ASP.orion_masterpage_master.__BuildControlBody() at ASP.orion_masterpage_master.__BuildControlTree(orion_masterpage_master __ctrl) at ASP.orion_masterpage_master.FrameworkInitialize() at System.Web.UI.UserControl.InitializeAsUserControlInternal() at System.Web.UI.MasterPage.CreateMaster(TemplateControl owner, HttpContext context, VirtualPath masterPageFile, IDictionary contentTemplateCollection) at System.Web.UI.Page.get_Master() at System.Web.UI.Page.ApplyMasterPage() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
I tried using the configuration wizard but of no help. Any one has seen this?
