Problem: The issue here is that the user is getting a warning about open_basedir whenever they activate the WooCommerce Bookings and WooCommerce Product Vendors when Woocommerce views is enabled.
Solution: The problem is that you server has an open_basedir restriction in place, and the WCV json file is being flagged because it’s not in one of the open paths.
I would recommend that you get in touch with your server team and ask them to modify the open_basedir server settings so this file can be opened.
