[Fermé] Home page not load correctly in other languages

Background of the issue:
I am trying to load the home page correctly in other languages using WPML. The page works fine in Greek (GR), but when I switch to English (EN) or German (DE), it doesn't load correctly. Here is the link to the page where the issue can be seen: lien caché.

Symptoms:
The home page does not load correctly in English and German. Instead of translated content and images, I see empty and oversized boxes.

Questions:
Why does the home page not load correctly in English and German?
How can I fix the issue of empty and oversized boxes on the translated pages?
