Background of the issue:
I am trying to display Greek language translations on my website, but they are not showing up in the dropdown menu. This issue started suddenly, even though it was working before. The Greek homepage at lien caché works, but the main site at lien caché is not available in the language switcher dropdown. This problem affects all pages and posts on the site.
Symptoms:
The dropdown only shows translations for English, not Greek, even though I expected to see both languages.
Questions:
Why are Greek translations not appearing in the dropdown?
How can I restore the Greek language option in the language switcher?
