OK. I’m surprised to hear that WooCommerce by itself would conflict in this way: one of our addons depends on WooCommerce and we regularly work with and test it – and have users who work with it in other languages – but haven’t been aware of any white-screen-of-death issues.
Perhaps the conflict lies a little deeper and relates to another addon or something of that order?
At any rate, it does sound like the problem lies with something other than The Events Calendar/Events Calendar PRO and with that in mind – and since you marked this as resolved – I will go ahead and close this thread.
If we can help with anything else, though, please don’t hesitate to create new threads as needed and one of the team will be only to happy to help 🙂
