Background of the issue:
I created an event in Basque, the main language of the website, and translated it as I always do. The translation indicates that it is complete, but the page does not exist on the website even though the URL seems correct. Link to a page where the issue can be seen: hidden link
Symptoms:
The translated event does not exist. The menus are not syncing, and I get a 'Sorry! That page does not exist.' message.
I have cleared caches, both in WPML and Wp-Rocket, I have also synchronized tables, taxonomies...etc.
Questions:
Why does the translated event indicate completion but not appear on the website?
How can I ensure the menus sync correctly to display the translated event?
