My client has a WordPress/Woocommerce site, with WOOF - WooCommerce Products Filter (version 2.1.4.2).
They have received a WordPress email advising them that this plug-in is causing a fatal eror, although when I check the site and use the product filter I am not encountering any obvious errors or issues.
Here is the relevant text from the email (edited for privacy):
