jquery freeze error continues after upgrade

Can you tell me more about the issue? What is actually happening? I’m not familiar with the issue, off hand.

I start putting the content. When I try to put the correct date, nothing happens, all freeze in screen.

Can you submit a support request? This is probably a plug-in or theme conflict.

I have the same problem here. When I click to select the date if freezes the browser window and I can’t even reload the page.

the error is when I click in the field below:

<input type=”text” id=”event_begin” name=”event_begin[]” class=”event_begin calendar_input” size=”11″ value=”2013-10-20″>

Well, I think the issue is caused by jQuery version (v1.10.2) used on the latest version of WordPress (mine is 3.6.1) as when I forced the Admin to use jQuery 1.9.1 it fixed the issue in Firefox (not in Chrome).

by the meantime you can put the code below on your theme’s functions.php and that will fix:

add_action( 'admin_enqueue_scripts', 'change_jquery_vrs' );
function change_jquery_vrs(){
    wp_deregister_script( 'jquery' );
    wp_register_script( 'jquery', ( '//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js' ), false, '1.9.1', false );
}

I’ve found that the issue is on the jquery.calendrical.js for users using the Brazilian Summer Time Zone on their system. And it only happens on Webkit browsers (I’ve tested only on Mac).

If put a file that shows 10 days of this month, one after another, using the setDate method of JavaScript.

In webkit browser it show to me:

You can see that there’s no day 20, and that’s making the script to go into a endless loop.

Thanks for the detailed documentation of the issue – that’s pretty obscure, but I’ll work on it.

Thanks, Padilha and Joe for your help!

@spadhila — Your link goes to an error page; can you provide that link again?

But you’ll only see the bug if you set your machine time zone to Brazil (S?o Paulo).

So, I just can’t seem to trigger this bug. I’m running your test script, on Chrome on a Mac, with the timezone set to Brazil/Sao Paolo – and I’m not seeing any problem. All dates are there, Oct 17 – Oct 31. I’ve also set up my own test, modifying the dates so that today’s date isn’t at the end of the sequence – but it’s still appearing fine.

Oddly, when I run your test script, everything shows up as GMT -0500, UTC; my copy of the same script shows up as GMT-0200 (BRST).

Not sure why that would be, since both scripts are running in the same browser, same OS.
