Problem: You are trying to manage multiple languages on your WordPress site using WPML, with Ukrainian as the main language. After changing the language code from 'uk' to 'ua' and duplicating content, you encountered several issues: HTTP ERROR 500 on blog pages in English and Russian, locks next to the ACF metaboxes on some posts, and incorrect language displays in the admin panel. Solution: 1. Ensure the new language is set as the original for your pages/posts. Edit each page, disconnect it from translation, reconnect, and set the correct default language. This might require re-translating some content. For detailed steps, visit WPML forum topic. 2. Disable all plugins except for WPML and Elementor to check if the issue persists. 3. Manually delete old language content and ensure everything is set correctly in the new default language. This includes checking and fixing default language templates and ensuring they are correctly assigned. 4. Be aware of a known bug where taxonomies are not deleted when removing content from the database. For more information, visit WPML errata on taxonomies.
If these steps do not resolve your issues or if the solution seems outdated or irrelevant to your specific case, please check related known issues at https://wpml.org/known-issues/, verify the version of the permanent fix, and confirm that you have installed the latest versions of themes and plugins. We highly recommend opening a new support ticket for further assistance at WPML support forum.
