Problem:
You are experiencing a performance issue on your WordPress site using WPML and ACF (Flexible Content + Repeaters), where the option
has grown to an unusually large size, primarily due to massive duplication in translation-management custom fields and terms.
Solution:
1) Update the ACF and ACFML plugins to their latest versions to ensure optimal performance and compatibility.
2) Review all ACF field groups to ensure they are properly configured. Remove unused fields or groups, ensure field names are unique within each group, and adjust translation preferences to 'Same fields across languages' where applicable.
3) Consider using a GitHub plugin to clean up the
option in the database. This can be tested on a staging copy of your site. However, please be aware that we are not the authors of this plugin and cannot guarantee its behavior.
If these steps do not resolve your issue or if the solution seems outdated or irrelevant to your specific case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the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. If necessary, please do not hesitate to open a new support ticket at WPML support forum for further assistance.
