Problem:
The client is unable to see changes on the frontend after editing a page translated into a custom language (NZ-EN), and changes also disappear from the CMS after refreshing the page. The issue was identified as a trailing slash redirection in the .htaccess file.
Solution:
We advised the client not to change the language code directly in the database as it could disrupt all language connections for that language. Instead, we recommended creating a custom language using the desired code (NZ-EN). To further investigate the issue, we provided a sandbox environment for the client to replicate the issue or share access to their live site. Here is the sandbox link: https://pretty-marimba.sandbox.otgs.work/?auto=LZ9F7w3EseacASA8Q8bmmQDHKYuGcH8R
