I am upgrading a portal that has 500+ child portals. the upgrade is being done following the recommended path on this site. http://www.dotnetnuke.com/Resources/Wiki/Page/Suggested_Upgrade_Path.aspx

Instance was at 4.8.2.

When upgrading from 6.2.6 to 7.0.2, the site settings page fails with the following error.

Error: Site Settings is currently unavailable.DotNetNuke.Services.Exceptions.ModuleLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Modules.Admin.Portals.SiteSettings.get_SelectedCultureCode() at DotNetNuke.Modules.Admin.Portals.SiteSettings.OnLoad(EventArgs e) --- End of inner exception stack trace ---

I have checked my web config and indeed it has globalization set for en-US. Must there be template files in the portals?

How do I fix this problem?

Host settings page also now fails with Error: Host Settings is currently unavailable.DotNetNuke.Services.Exceptions.ModuleLoadException: f:\internetDataStorage\secureSharesDev\DesktopModules\Admin\HostSettings\HostSettings.ascx.cs(702): error CS0029: Cannot implicitly convert type 'DotNetNuke.Services.Scheduling.ScheduleItem' to 'ScheduleItem' ---> System.Web.HttpCompileException: f:\internetDataStorage\secureSharesDev\DesktopModules\Admin\HostSettings\HostSettings.ascx.cs(702): error CS0029: Cannot implicitly convert type 'DotNetNuke.Services.Scheduling.ScheduleItem' to 'ScheduleItem' at System.Web.Compilation.BuildManager.PostProcessFoundBuildResult(BuildResult result, Boolean keyFromVPP, VirtualPath virtualPath) at System.Web.Compilation.BuildManager.GetBuildResultFromCacheInternal(String cacheKey, Boolean keyFromVPP, VirtualPath virtualPath, Int64 hashCode, Boolean ensureIsUpToDate) at System.Web.Compilation.BuildManager.GetVPathBuildResultFromCacheInternal(VirtualPath virtualPath, Boolean ensureIsUpToDate) at System.Web.Compilation.BuildManager.GetVPathBuildResultInternal(VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile, Boolean throwIfNotFound, Boolean ensureIsUpToDate) at System.Web.Compilation.BuildManager.GetVPathBuildResultWithNoAssert(HttpContext context, VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile, Boolean throwIfNotFound, Boolean ensureIsUpToDate) at System.Web.Compilation.BuildManager.GetVPathBuildResult(HttpContext context, VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile, Boolean ensureIsUpToDate) at System.Web.UI.TemplateControl.LoadControl(VirtualPath virtualPath) at DotNetNuke.UI.ControlUtilities.LoadControl[T](TemplateControl containerControl, String ControlSrc) at DotNetNuke.UI.Modules.WebFormsModuleControlFactory.CreateModuleControl(TemplateControl containerControl, ModuleInfo moduleConfiguration) at DotNetNuke.UI.Modules.ModuleControlFactory.LoadModuleControl(TemplateControl containerControl, ModuleInfo moduleConfiguration) at DotNetNuke.UI.Modules.ModuleHost.LoadModuleControl() --- End of inner exception stack trace ---
