Hi Blandine,
So sorry for the trouble here with your license keys! Let’s check this out together and see what’s up.
I see that you have purchased Event Tickets Plus, but I do not see that it is currently installed on your site. Here is what I do see installed:
- The Events Calendar 4.3.1.1
- Event Tickets 4.3.1.1
If you install Event Tickets Plus, then the license key screen should show a field for you to Enter the license for Event Tickets Plus as well.
Please give that a try and let me know if it does the trick. 🙂
Thanks!
Geoff
