[مغلق] Translation not showing on website's pages

Background of the issue:
I am trying to translate my website's pages from Greek to English using WPML. I pressed the "+" button to add translations, entered the English text, and added a language switcher to the menu to verify the translation.

Symptoms:
The translated pages are not showing; instead, the pages remain in the original language (Greek).

Questions:
Why are the translated pages not displaying correctly?
How can I ensure the language switcher works as expected?
