This thread is resolved. Here is a description of the problem and solution.
Problem:
The client was experiencing 404 errors on newly published translated pages and products with incorrect or inconsistent permalinks.
Solution:
We recommended checking if the permalinks 'slugs' were correctly translated using the String Translation. It was suggested to reset these URLs to their default settings and then properly translate them. Additionally, we advised deactivating all plugins except WPML and switching to a default WordPress theme to identify any conflicts causing the issue. If the problem persisted, the next step was to create a staging site to further diagnose and resolve the issue without affecting the live site. After these steps, if issues with permalinks still occurred, it was necessary to ensure that slugs for different post types and categories were unique to avoid conflicts.
If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, we highly recommend opening a new support ticket. 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. For further assistance, you can also contact us directly at the WPML support forum.
