Hi George, I have the same issue but it could have a litte different start because i have just started those translations. Before install all WPML plugins Woocommerce endpoints works correctly. After install WCML endpoits had broken. After translate them to Polish they still not working. I have did what you said in previous posts (save in admin, patch in files) but it’s not working for me still. Do you have any other fix i could make?
