The called constructor method for WP_Widget is deprecated since version 4.3.0

Question

I just updated to WordPress 4.3 and it seems that something is broken.

I get this error that shows up on my page:

Notice: The called construct

Answer 1

Declaring a function then calling the parent constructor resolved this issue for me.

class myClass extends WP_Widget {
  function __construct(){
     parent::__construct(...) // calls constructor from WP_Widget class
  }
}
