Problem:
If you're experiencing issues with media items not appearing in the WordPress media library when using WPML Multilingual CMS version 4.8.1 and WPML String Translation 3.4.0, it might be due to incorrect usage of the language switcher in the top-bar. This can lead to media items being hidden or not displayed as expected.
Solution:
We recommend using the WPML Translation Editor to manage your media items and translations. Avoid switching languages directly from the top-bar as it can disrupt the proper display and management of media items. Instead, use the language switcher in the Media Library menu to view media entries in different languages. For editing pages in multiple languages, create the page in one language and use the '+' symbol in the WPML Translation Editor to add translations for other languages. This ensures all media and content are correctly linked and displayed.
