Problem: The client is experiencing a significant slowdown in the WordPress dashboard when using WPML, particularly when saving menus, which can take over 50 seconds to load.
Solution: First, we recommend updating to the latest version of WPML Multilingual CMS, as version 4.6.9 includes performance improvements. To update, navigate to Plugins > Add New > Commercial and click on "Search for WPML Updates". You can also download the latest versions directly from your WPML account downloads page.
If updating does not resolve the issue, we suggest running WPML > WP Menus Sync to reduce the number of duplicated queries. You can find a guide on how to do this here: Translating Menus.
Additionally, use the troubleshooting options under WPML > Support > Troubleshooting to sync post taxonomies and clear the WPML cache. More information on these options can be found here: WPML Troubleshooting Options.
After these steps, the client should see a significant reduction in duplicated queries and improved performance.
Please note that this solution might be outdated or not applicable to your specific case.
