Problem: The client is implementing WPML with Advanced Custom Fields (ACF) Multilingual and seeks confirmation on best practices for field translation settings, ensuring layout elements sync across languages, and maintaining a scalable multilingual structure. Solution: We recommend setting ACF Field Groups to 'Not translatable' and choosing the appropriate translation preferences for fields: use 'Copy' for layout/structure fields (like repeaters, icons, CTAs) to maintain synchronization across languages, and 'Translate' for user-facing text fields to allow proper content translation. It's important not to manage ACF fields from the WPML → Settings → Custom Fields Translation screen but directly from the ACF Field Group edit screen. The fields listed there, including dynamically created ones, are normal for ACF-based sites and should remain as configured without manual adjustments. For detailed guidelines, refer to ACF Field Groups translation settings and recommended custom fields translation preferences for ACF and WPML.
If this solution does not fully address your issue or seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.
