Problem: The client is unable to edit image fields in the Spanish version of their site when they are part of a flexible content field. After changing the ACF translation settings from 'copy' to 'copy once', the images also became uneditable on the English side, and reverting the settings did not resolve the issue. Solution: We recommend setting the field preference to 'Copy Once' and using the WordPress editor to manually update the custom field in the translation post. This should allow for editing the image fields in both the English and Spanish versions of the site.
