AutoBlog Add-On (Replace Author Information) WP_Widget error

When activating the AutoBlog Add-On (Replace Author Information) I get a white screen and the debug issues the WP_Widget deprecated error. FYI

Notice: The called constructor method for WP_Widget is deprecated since version 4.3.0! Use
__construct()
instead. in /home/commit89/public_html/wp-includes/functions.php on line 3624

Please update add-on
Thanks!
