I'm experiencing a problem after update joomla! to version 3.8.6, the module menuwrench no load submenu items.
The option "Show Sub-menu Items" its ok.

In error.php

PHP Notice: Indirect modification of overloaded property Joomla\CMS\Menu\MenuItem::$children has no effect in /var/www/unm/modules/mod_menuwrench/helper.php on line 84,

In line 84 and context:

`
$this->app = joomla\CMS\factory::getApplication();
$this->db = joomla\CMS\factory::getDbo();

$this->menu = $this->app->getMenu();
$items = $this->menu->getItems(null, null);

foreach ($items as $key => $item)
{

        $items[$item->id] = $item;

        // If menu item is a category, add all articles as menu items
        if ($showCategoryItems && $this->isContent($item))
        {
            $items[$item->id]->hijo = $this->linkCategoryItems(
                $this->getCategoryItems($item->query['id']),
                $item->query['id'],
                $item->id
            );
        }

        unset($items[$key]);

        if ($item->parent_id != 1)
        {
            $items[$item->parent_id]->hijo[$item->id] = $item; <--Line 84
        }
    }

`

Expected result

mod_menuwrench is not a core module and you should contact the people who made it or ask for help on the forum https://forum.joomla.org

You would have to ask Matt @betweenbrain to update their core improvement module. Not default joomla. Look at https://extensions.joomla.org/extensions/extension/structure-a-navigation/menu-systems/menu-wrench/ and support options mentioned there
