Error plugin Which does not work

[biaf]

Hello,

I bought a plugin WooCommerce TM Extra Product Options
And the options I put do not work.
I tested it on another template and walked it.

Do you think its comes from these mistakes? And how do I have to correct these errors?

my web site: https://www.kbs-fermeture.fr/produit/sandra/

Notice: La méthode du constructeur appelée pour WP_Widget dans WPAC_Nav_Menu_Widget est obsolète depuis la version 4.3.0 ! Utilisez

__construct()

à la place. in /home/kbsferme/public_html/wp-includes/functions.php on line 3894

and

Notice: get_currentuserinfo est obsolète depuis la version 4.5.0 ! Utilisez wp_get_current_user() à la place. in /home/kbsferme/public_html/wp-includes/functions.php on line 3831

and

Warning: Cannot modify header information - headers already sent by (output started at /home/kbsferme/public_html/wp-includes/functions.php:3894) in /home/kbsferme/public_html/wp-includes/pluggable.php on line 1210

In woocommerce It also mistakes me (see screenshot)

Thank you for your help,

Regards,
