Problem: If you're experiencing issues on your production site where custom fields like 'downloads_*_url_pardot' show a lock icon in WPML > Settings > Custom Fields Translation, preventing you from setting their translation behavior to "Copy", while on your staging environment these fields do not have this lock and can be set to Copy normally. Solution: First, ensure that the 'acf-field-group' post type is set to not translatable in WordPress Dashboard > WPML > Settings > Post Types Translation. If it's already set, no changes are needed there. Next, make a minor edit to the original page (like adding an extra space) and save it. This should prompt an update across translations. If the issue persists, check for any XML code under WordPress Dashboard > WPML > Settings > XML Custom Code tab that might be forcing the lock icon. Also, verify if such XML files exist in your theme or plugin files. If you find the settings are correct but the problem remains, it might be due to the field group settings in ACF > Field Groups > Knowledge Base group field translation option, which should be set to Expert mode to allow changes in custom field translation options. After adjusting these settings, make a small change on the page using the field in the original language and complete the translation to see the results.
