Hi,
I am working on SP 2010 Advance search page. When I try to view the page I get "Object reference not set to an instance of object". Then I go and preview the webpart advancesearchbox.dwp. It also throws the same error. Other search webparts does not throw any error.
Error in ULS logs,
System.Configuration.ConfigurationErrorsException: Unrecognized attribute 'allowInsecureTransport'. Note that attribute names are case-sensitive. (C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\WebClients\SecurityToken\client.config line 40) at System.Configuration.BaseConfigurationRecord.EvaluateOne(String[] keys, SectionInput input, Boolean isTrusted, FactoryRecord factoryRecord, SectionRecord sectionRecord, Object parentResult) at System.Configuration.BaseConfigurationRecord.Evaluate(FactoryRecord factoryRecord, SectionRecord sectionRecord, Object parentResult, Boolean getLkg, Boolean getRuntimeObject, Object& result, Object& resultRuntimeObject) at System.Configuration.BaseConfigurationRecord.GetSectionRecursive(String configKey, Boolean getLkg, Boolean checkPermission, Boolean getRuntimeObject, Boolean requestIsHere, Object& result, Object& resultRuntimeObject) at System.Configuration.ConfigurationSectionCollection.Get(String name) at System.ServiceModel.Configuration.ServiceModelSectionGroup.get_Client() at Microsoft.SharePoint.Administration.Claims.SPSecurityTokenServiceApplication.get_Binding() at Microsoft.SharePoint.SPChannelFactoryOperations.ConfigureCredentials[TChannel](ChannelFactory`1 factory, SPServiceAuthenticationMode authenticationMode) at Microsoft.Office.Server.Search.Administration.SearchServiceApplicationProxy.CreateChannelFactory[T](String endpointConfigurationName) at Microsoft.Office.Server.Search.Administration.SearchServiceApplicationProxy.GetChannel(Uri address, Int32 timeoutInMilliseconds) at Microsoft.Office.Server.Search.Administration.SearchServiceApplicationProxy.GetChangedConsumers(Int64& lastChangeTimeStamp) at Microsoft.Office.Server.Search.Administration.RemoteScopes.GetConsumerChanges(Int64& lastChangeTimeStamp) at Microsoft.Office.Server.Search.Query.ScopeCache.PollForChanges(ScopeCache scopeCache) at Microsoft.Office.Server.Search.Query.ScopeCache.RefreshScopeCache(String key) at Microsoft.Office.Server.Utilities.SPAsyncCache`2.GetValueNow(K key) at Microsoft.Office.Server.Utilities.SPAsyncCache`2.Callback(Object state)
