Problem: If you're experiencing a 404 error on translated product category pages using WPML, it might be due to issues with your permalink settings or slug translations. Solution: 1) Verify that there are translated products within the category in question. 2) Use distinct slugs for different languages; avoid using the same slug, such as "magazine", in both languages. 3) If the problem persists, consider setting up a staging site to isolate the issue. On this site, use the default WordPress theme and enable only the WPML plugins and WooCommerce, while disabling all other plugins. 4) Ensure that all your themes and plugins, especially WPML and WooCommerce, are updated to their latest versions.
If these steps do not resolve the issue, or if the solution seems outdated or irrelevant to your specific case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the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. Additionally, you can open a new support ticket for further assistance at WPML support forum.
