Yep, same here (I already reported it, but the system held my topic, for some peculiar reason). I got this error notice:
Notice: wp_register_style was called incorrectly. Scripts and styles should not be registered or enqueued until the wp_enqueue_scripts, admin_enqueue_scripts, or login_enqueue_scripts hooks. Please see Debugging in WordPress for more information. (This message was added in version 3.3.0.) in \wp-includes\functions.php on line 4146
Notice: wp_enqueue_style was called incorrectly. Scripts and styles should not be registered or enqueued until the wp_enqueue_scripts, admin_enqueue_scripts, or login_enqueue_scripts hooks.

Fatal error: Call to undefined function WC() in \wp-content\plugins\wc-fields-factory\includes\wcff-product-fields.php on line 78
This notice above appears if WooCommerce is not activated, so I guess some check for WC plugin activation would be needed.
But when WC is activated I got this message:

No other plugins are activated, and default TwentySeventeen theme is active.
Thanks
