Good evening Mathieu and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the events not showing up for the organizers.
I would love to help you with this topic.
As a starting point, if you have not done so already, I highly recommend reading and using the following guides:
- https://theeventscalendar.com/knowledgebase/setting-up-the-events-calendar-with-wpml/
- https://theeventscalendar.com/knowledgebase/creating-translations-for-events-using-wpml/
Head over to WPML > Support > Troubleshooting page.
Once you are there, you should see several cleanup buttons. I would recommend:
- Clearing WPML cache
- Using ALL the cleanup buttons located at the top of that page (including synchronize post taxonomies)
- Re-saving your permalinks
Let me know how that goes.
Best regards,
Geoff B.
