Hi Vince,
Thanks for reaching out! Unfortunately, Event Tickets and Event Tickets Plus do not currently have support for WPML, although we are working on improving this in the future. Sorry for the bad news there!
However, I’m not quite sure what you are referring to here when you say that the tickets don’t exist on the admin’s product listing…could you please provide some more details on what is going wrong? Do you mean that the tickets are not being saved on the event? Any screenshots of the issue that you have would be helpful as well!
It sounds like you may have found an old thread from another user who was experiencing a similar issue? If so, can you please link to it here?
Thanks,
Jennifer
