Hi Edgar,
My apologies for a rough start here with Event Ticket Plus! I really do appreciate that you’ve reported this and that you went through the process of testing for conflicts — that helps a ton.
I am afraid that Event Tickets is not compatible with WPML at the moment. We have put a lot of effort into integrating The Events Calendar itself with WPML, but Event Tickets and Event Ticket Plus are not fully there and it really is a huge lift to get it going, though it is something we are definitely wanting to do.
Sorry for the bad news, but does this help shed some light on the issue? I can understand the frustration here since your site definitely needs to support multilingual content, so let me know if this is a deal-breaker, and I would be happy to refund your purchase, as long as it’s within our 30-day window for returns. Let me know and I can get that going.
Thanks,
Geoff
