Hi,
I had the same problem with activated plugins (Woo & Product Add-ons). I am using multisite and you addon does not understand if plugin has been network-activated. So this is the procedure I got it working via CLI (you can do it via backend if you prefer clicking):
(
wp plugin deactivate woocommerce –network
wp plugin deactivate woocommerce-product-addons –network
wp plugin activate woocommerce
wp plugin activate woocommerce-product-addons
wp plugin activate woocommerce-product-addons-variable-release –network
wp plugin activate woocommerce –network
wp plugin activate woocommerce-product-addons –network
)
Commands speak for themselves.
