Problem: The client was unable to update ACF option fields on their multilingual site, experiencing critical errors and crashes when attempting to save changes. Additionally, there were issues with editing image fields on translated pages, where the edit/delete icons were not appearing.
Solution: We discovered inconsistencies in the database where serialized content was stored incorrectly for the English options, while only layout references existed for the original German version. This issue was compounded by field group assignments that did not align with the Options page, causing duplicated data in the database. To resolve this, we performed a cleanup using the following SQL query:
DELETE FROM wp_bbjeklgvta_options WHERE option_name LIKE '%sections_jobs%';
We recommend the client to ensure a full backup of their website before attempting similar database modifications. Additionally, reviewing the field group translation settings is advised to maintain consistency across languages. If using Expert mode, it's crucial to align all settings with our documentation to prevent further issues.
