[Chiuso] Translated pages not displaying correctly when switching languages (WPML)

I am experiencing an issue with WPML translations.
Most of my site pages are already translated and marked as “Translation completed” in WPML. However, when I switch the website language on the front end, the pages still appear in the original language instead of the translated version.
This happens even though:
- All affected pages show their translations as completed in WPML
- The correct languages are configured
- The translations exist and are visible in the WPML translation editor
I have spent approximately 20,000 WPML credits on these translations, so this issue is critical for me.
I would appreciate your help to understand why the translated content is not being displayed on the front end and how to fix it.
Please let me know if you need access details, screenshots, or specific page examples.
