This thread is resolved. Here is a description of the problem and solution.
Problem:
You are trying to display the same ACF field values across all languages on your WordPress site using WPML, but the option field is not displaying the expected value in other languages, showing null instead.
Solution:
1. Verify ACF Field Group Translation Settings
Go to ACF → Field Groups. Edit the field group associated with the affected content. In the Multilingual Content Setup section, ensure the Translation Option is set to “Same fields across languages”. Click Update to apply the changes.
2. Configure Individual Field Translation Preferences
Navigate to WPML → Settings. Scroll to the Custom Fields Translation section. Locate each ACF field used in the group. Set translation preferences as follows:
• Textual fields (e.g., text, textarea): Translate
• Media fields (e.g., images): Copy
• Repeater or flexible content fields: Copy
Click Save to confirm changes.
3. Update and Translate the Default Language Content
Edit the original post or page (in the default language). Make a minor change (e.g., add a space or line break) to trigger a content update. Save the changes. Open the WPML Translation Editor and re-translate the content.
4. Clear WPML Cache
Go to WPML → Support → Troubleshooting. Click “Clear the cache in WPML”.
