I am with the same problem, I am using the version 0.20.1, I believe this plugin is with conflit with the JetPack Plugin, when I am desactivate the JetPack plugin, the Woocommerce Panel works, but when I Active the JetPack and click in Woocommerce Panel, the server go downfor aproximadally 5 min – 7 min.
I liked this Plugin, I really wish that this problem fix, but while this problem don’t fix, I will mantein this plugin desactived, because I can’t risk my server go down.
