Bug in Month View

When Option “show_all_event_days” is set to yes, only these Items are displayed in Month View wich have an end date.
So solve this you can edit helper-function.php function aec_get_dates_from_range()
Insert after $interval = ….:

    if ($end == "0000-00-00") {
       $end = $start;
    }

Thats it. Other Views are not used by me so maybe it is the same.
