Hi everybody, I am also getting this error.
I have Woocommerce 3.2.4 installed and if I deactivate it the cornerstone editor will load so this appears to be the conflict. As an eCommerce store I kind of need it to be activated to actually run the business. Is there a way of resolving this at all with the latest version of Woocommerce or is there a way of downgrading it to the compatable version??
