Problem: If you're experiencing content duplication with WPML when using translated taxonomies in URLs, where using a taxonomy translation in the URL displays the same content but doesn't redirect to the original URL, this summary is for you. Solution: First, we recommend updating your WPML plugin to the latest version (4.6.11) and all related add-ons to ensure you have the latest bug fixes and improvements. You can find the latest versions under 'My Account -> Downloads' on the WPML site. Detailed instructions for updating can be found here: http://wpml.org/faq/install-wpml/. Ensure to back up your database before proceeding with the update. You might consider using a plugin like Duplicator (http://wordpress.org/plugins/duplicator/). After updating, if the issue persists, try deactivating non-WPML plugins to check if the problem still occurs. Unfortunately, as of now, there is no available workaround for this specific issue. However, our development team is aware and working on a fix. You can monitor the status of this issue here: https://wpml.org/errata/wpml-translated-posts-accessible-through-original-language-category/.
If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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. If the problem persists, please open a new support ticket at WPML support forum.
