When woocommerce subscriptions plugin is active... you're unable to access single entry pages in any view. It throws a 404 page not found error. When I deactivate woocommerce subscriptions, it doesn't do that.
When I downgrade the subscriptions plugin to an older version, it works fine. This is the same issue I'm having with GravityFlow as well. I have already reported the bug to them.
