I don't know how to enable editing the created date of an article in the front-end, after updating to Joomla 3.8.10.

So far I used to override the article's edit form

com_content -> form > edit #line 120 :

<?php echo $this->form->renderField('created'); ?>

as suggested in this article: How to edit 'created date' from front end, and all was fine.

However, this no longer works with version 3.8.10.

How can I do it?

Created field in frontend article form contains unset filter. This filter prevents field value from saving. You can change the filter with a content plugin. The example below also sets showtime attribute to true in case you want to enter time like in other date fields.

defined('_JEXEC') or die;

use Joomla\CMS\Form\Form;
use Joomla\CMS\Plugin\CMSPlugin;

class PlgContentExample extends CMSPlugin
{
    protected $app;

    public function onContentPrepareForm(Form $form, $data)
    {
        if ($this->app->isClient('site') && $form->getName() === 'com_content.article')
        {
            $form->setFieldAttribute('created', 'filter', 'user_utc');
            $form->setFieldAttribute('created', 'showtime', 'true');
        }

        return true;
    }
}

Note, the template override is still required to render the field.
