Navigator not right

Can you please post your config? It looks like it only happens with a specific configuration (the online demo at https://javascript.daypilot.org/demo/calendar/navigator.html works fine).

Here's my code:

var nav = new DayPilot.Navigator("nav");
nav.showMonths = 1;
nav.selectMode = "day";
nav.onTimeRangeSelected = function(args) {
loadTimeline(args.start);
loadEvents(); //my function to load the event
};
nav.init();

Thanks - unfortunately, I'm not able to reproduce the bug using the latest version. What DayPilot version do you use?

1729. Is there a more recent version?

Yes, the latest version is 8.3.2848:

https://javascript.daypilot.org/try/

Did you download it as part of a tutorial? It may need an update - could you please let me know the URL?

I've download the version 2848 and still have the problem

Yes I download this tutorial https://code.daypilot.org/27988/html5-calendar-with-day-week-month-views-javascript-php and modify it as I wanted. Do you want all my code in my page to check?

You may need to force a full reload of the browser - sometimes the old version gets cached.

Or do you see the problem in the online demo as well?

    var nav = new DayPilot.Navigator("nav");
    nav.showMonths = 3;
    nav.skipMonths = 3;
    nav.selectMode = "week";
    nav.freeHandSelectionEnabled = true;
    nav.onTimeRangeSelected = function(args) {
        console.log(args);
        dp.startDate = args.start;
        dp.update();
    };
    nav.onBeforeCellRender = function(args) {
        if (args.cell.isCurrentMonth) {
            args.cell.cssClass = "current-month";
        }
    };
    nav.init();

Changing it to your config doesn't reproduce the bug for me.

Let me know if it didn't help.

You're right, needed to empty cache, should have tough about it thanks.

Great, thanks for the update. Let me know if there is any problem.
