Does PUT and DELETE return error 401 in a WCF Restful service?

POST and GET requests work in the same web service. But no PUT and DELETE, I have placed the authentication as "None" but it still does not work.

The interface is as follows:

    [OperationContract]
    [WebInvoke(Method = "PUT", RequestFormat = WebMessageFormat.Json,
        ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare,
        UriTemplate = "/ModificarEvento/{idEvento}/{fechayHoraDeEnvio}/{fechayHoraDeLlegada}/{fechayHoraDeSalida}/{causaEvento}/{observacion}/{asistenciaPolicial}/{supervisionExterna}/{idTipoEvento}/{idEstadoEvento}/{idCliente}/{idPersona}/{idSupervisor}/{idOperador}")]
    int ModificarEvento(string idEvento, string fechayHoraDeEnvio, string fechayHoraDeLlegada, string fechayHoraDeSalida, string causaEvento, string observacion, string asistenciaPolicial, string supervisionExterna, string idTipoEvento, string idEstadoEvento, string idCliente, string idPersona, string idSupervisor, string idOperador);

    [OperationContract]
    [WebInvoke(Method = "GET", RequestFormat = WebMessageFormat.Json,
         ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare,
         UriTemplate = "/ListarUltimosEventos/{aliasUsuario}/{descripcionEstadoEvento}")]
    List<EventoWCF> ListarUltimosEventos(string aliasUsuario, string descripcionEstadoEvento);

The web.config is found as follows:

The result of consuming the PUT request comes out as follows:
