Problem:
The user encountered a blank page when trying to add a language switcher to the menu bar (header) in the Betheme. The menu was translated, but the issue persisted. The supporter identified that the main menu was not translated, leading to the problem.

Solution:
The supporter recommended translating the main menu using the steps provided in the WPML documentation. After the menu was properly translated, the user could add the language switcher without encountering a blank page. Additionally, the supporter suggested checking for plugin compatibility, and the user found a compatibility issue with the Easy Yandex Metrica plugin. Deactivating and reactivating the problematic plugin resolved the issue.
