Thanks for the update Karine 🙂
As Geoff states in his reply Event Tickets Plus is not fully compatible with WPML. We are working closely with the WPML compatibility team to address this, but unfortunately it’s a pretty slow process 🙁
I can make some test in my local install to see if the’res a viable way to make them work at least. Anyway please note that we won’t be able to support any issues as both plugins are not compatible at the time.
If you think this is a show-stopper for you and would like to request a refund, that’s totally fine!
Please let me know about it,
Best,
Nico
