Critical Problems:

* The Plugin “WooCommerce” needs an upgrade.

NOTE: You are using the free version of Wordfence. Upgrading to the paid version of Wordfence gives you two factor authentication (sign-in via cellphone) and country blocking which are both effective methods to block attacks. A Premium Wordfence license also includes remote scanning with each scan of your site which can detect several additional website infections. Premium members can also schedule when website scans occur and can scan more than once per day.

As a Premium member you also get access to our priority support system located at http://support.wordfence.com/ and can file priority support tickets using our ticketing system.

Jadi pertanyaan saya :
1.Apakah saya harus meng-update Woocommerce?
2.Cara backup data untuk jaga-jaga hal yang tidak diinginkan bagaimana ya?
3.Di Wordpress ada juga peringatan untuk update plugin-plugin,apakah saya harus mengupdate plugin-plugin tersebut?
Segitu dulu untuk pertanyaanya,besuk nyambung lagi kalau ada tambahan.
Terimakasih
