Problem: The client was experiencing an issue where translated slugs were not updating on the live site, resulting in a 404 error for the expected translated URL. Solution: We recommended the client to ensure that the 'Translate' option for Page URL settings is enabled in WPML > Settings > Translated documents options > Page URL. This setting allows the slug to be included in the translation rather than being automatically created from the title. After enabling this, the client should resave the primary language page, which prompts the Advanced Translation Editor to rescan the page and display the URL slug for translation. If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.
