Hi,
I just purchased the pro version of your plugin and as soon as I activated it my multilingual site shows error 500 at the checkout of every secondary language.
i deleted cache, and reset permalink with no luck.
I tried it the on a different installation updated to the last WPML and Wooccommerce update (released today), but still shows up error 500.
I then disabled your plugin and everything works fine. The lite version works fine too but i need the pro version to work.
Site is in production, would you please help me out?
