Unfortunately I think so. Many people are receiving the following error:
PHP Notice: The called constructor method for WP_Widget in WPAC_Nav_Menu_Widget is deprecated since version 4.3.0! Use
__construct()
instead. in [path redacted]/wp-includes/functions.php on line 3902
This plugin uses PHP4 style constructors for widgets. As a temporary fix the following changes can be made to the plugin.
Within “default-widgets.php” lines 25 – 30 should be changed as follows:
function __construct()
{
$widget_ops = array( ‘description’ => __(‘Use this widget to add one of your custom menus as a widget.’) );
parent::__construct( ‘nav_menu’, __(‘Custom Menu’), $widget_ops );
Of course with all changes run this under a development environment first to ensure that it resolves your issue before moving to live
Let me know if you find a good alternative plugin
