I just tried to create a new parent portal on my installation and chose the 'Default Website' template. When I click the Create Portal link I get the following error:

Error parsing Admin TemplateProcedure or function 'DNN_AddTab' expects parameter '@PermanentRedirect', which was not supplied. The statement has been terminated. at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj) at System.Data.SqlClient.SqlDataReader.ConsumeMetaData() at System.Data.SqlClient.SqlDataReader.get_MetaData() at System.Data.SqlClient.SqlCommand.FinishExecuteReader(SqlDataReader ds, RunBehavior runBehavior, String resetOptionsString) at System.Data.SqlClient.SqlCommand.RunExecuteReaderTds(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, Boolean async) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, DbAsyncResult result) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method) at System.Data.SqlClient.SqlCommand.ExecuteScalar() at Microsoft.ApplicationBlocks.Data.SqlHelper.ExecuteScalar(SqlConnection connection, CommandType commandType, String commandText, SqlParameter[] commandParameters) at Microsoft.ApplicationBlocks.Data.SqlHelper.ExecuteScalar(String connectionString, CommandType commandType, String commandText, SqlParameter[] commandParameters) at Microsoft.ApplicationBlocks.Data.SqlHelper.ExecuteScalar(String connectionString, String spName, Object[] parameterValues) at DotNetNuke.Data.SqlDataProvider.AddModule(Int32 PortalID, Int32 ModuleDefID, String ModuleTitle, Boolean AllTabs, String Header, String Footer, DateTime StartDate, DateTime EndDate, Boolean InheritViewPermissions, Boolean IsDeleted) at DotNetNuke.Entities.Modules.ModuleController.AddModule(ModuleInfo objModule) at DotNetNuke.Entities.Modules.ModuleController.DeserializeModule(XmlNode nodeModule, XmlNode nodePane, Int32 PortalId, Int32 TabId, PortalTemplateModuleAction mergeTabs, Hashtable hModules) at DotNetNuke.Entities.Tabs.TabController.DeserializePanes(XmlNode nodePanes, Int32 PortalId, Int32 TabId, PortalTemplateModuleAction mergeTabs, Hashtable hModules) at DotNetNuke.Entities.Tabs.TabController.DeserializeTab(String tabName, XmlNode nodeTab, TabInfo objTab, Hashtable hTabs, Int32 PortalId, Boolean IsAdminTemplate, PortalTemplateModuleAction mergeTabs, Hashtable hModules) at DotNetNuke.Entities.Tabs.TabController.DeserializeTab(XmlNode nodeTab, TabInfo objTab, Hashtable hTabs, Int32 PortalId, Boolean IsAdminTemplate, PortalTemplateModuleAction mergeTabs, Hashtable hModules) at DotNetNuke.Entities.Portals.PortalController.ParseTab(XmlNode nodeTab, Int32 PortalId, Boolean IsAdminTemplate, PortalTemplateModuleAction mergeTabs, Hashtable& hModules, Hashtable& hTabs, Boolean IsNewPortal) at DotNetNuke.Entities.Portals.PortalController.ParseTabs(XmlNode nodeTabs, Int32 PortalId, Boolean IsAdminTemplate, PortalTemplateModuleAction mergeTabs, Boolean IsNewPortal) at DotNetNuke.Entities.Portals.PortalController.ParseTemplate(Int32 PortalId, String TemplatePath, String TemplateFile, Int32 AdministratorId, PortalTemplateModuleAction mergeTabs, Boolean IsNewPortal) at DotNetNuke.Entities.Portals.PortalController.CreatePortal(String PortalName, String FirstName, String LastName, String Username, String Password, String Email, String Description, String KeyWords, String TemplatePath, String TemplateFile, String HomeDirectory, String PortalAlias, String ServerPath, String ChildPath, Boolean IsChildPortal)

Not sure what's going on here. I did recently do an upgrade to 4.9.4 but that seemed to go ok. Does this error mean that I haven't updated a template file in the Portals/_default/ folder? If so, which ones do I need to update from this error?

thanks
