Problem: The client is experiencing an increase in 404 errors, redirect errors, and duplicate/canonical issues on their multilingual travel and culture blog after publishing new content using WPML. Solution: If you're encountering similar issues, we recommend the following steps: 1) Ensure you take a full backup of your site and database. It's advisable to perform these steps on a development or staging site first. 2) Enable debugging on your site. For details, see https://wpml.org/documentation/support/debugging-wpml/. This will log errors in the debug.log file, which you can then share for further investigation. 3) Deactivate all plugins except for WPML and String Translation. 4) Switch to a standard theme, such as 2024 or 2021. 5) Rename your .htaccess file and regenerate the default WordPress .htaccess by navigating to WordPress Dashboard -> Permalinks and saving without making changes. 6) Re-activate your plugins one by one to identify any conflicts. 7) If the issue resolves, reactivate your original theme to check if it is the source of the problem.
If these steps do not resolve your issue or if the solution seems outdated or irrelevant to your specific case, please check related known issues at https://wpml.org/known-issues/, verify the version of the permanent fix, and confirm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. We highly recommend opening a new support ticket for further assistance at WPML support forum.
Problem: The client experienced 404 errors and missing admin panel lists for posts, pages, and custom post types after activating the WPML plugin on their production site, despite the staging site working correctly. Solution: 1. We recommended creating a staging site using the WP Staging plugin to safely replicate the issue without affecting the production environment. 2. After verifying that the WPML plugins were not causing the 404 errors on the staging site, we suggested manually checking the WPML tables in the database, which appeared correct. 3. We advised the client to try reproducing the 404 errors by activating the theme and plugins one by one to identify the problematic component. 4. If the issue persisted, we recommended manually uploading the WPML plugins via the Plugins section in the WordPress admin. 5. We identified missing tables related to WPML in the database on the production site and fixed them.
If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, please visit our known issues page and ensure you have the latest versions of themes and plugins installed. If the problem continues, we highly recommend opening a new support ticket at WPML support forum.
