This thread is resolved. Here is a description of the problem and solution.
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If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, please visit our known issues page and ensure you have the latest versions of themes and plugins installed.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.
