Month not shown

[ernstralek]

Here is my setup:
var today= new Date(); daterange=$('#date-range').datepicker({ type:'date-range', format:'dd/MM/yyyy', lang:'es-AR', placeholder:'Seleccione un rango de fechas', rangeSeparator:' a ', endDate:today, onChange:function(event){ var dates=event.newDate.split(' a '); startDate= dates[0].trim(); finishDate= dates[1].trim(); } });

The previous month button doesn't works. I can't go to september. It seems to be because today is 31 and the previous month only has 30 days.

When I go back 1 year and then advance by month, September is not shown:
