Problem: The client is experiencing a performance issue on their website, where the database CPU utilization reaches 100% during the creation or updating of posts. They suspect that WPML may be contributing to this issue. Solution: We recommend the following steps to isolate the cause of the high CPU usage: 1. Create a full site backup or set up a staging site using a plugin like WP Staging. 2. Update any outdated plugins or themes. 3. Flush any existing cache memory. 4. Deactivate all plugins, including WPML ones. 5. Activate a default WordPress theme, such as Twenty Twenty. 6. Enable WordPress debug mode by following the guide at https://developer.wordpress.org/advanced-administration/debug/debug-wordpress/ 7. Reactivate the WPML plugins. 8. If the issue is resolved, reactivate the theme and other plugins one by one to identify the culprit. 9. Check for any errors related to the performance issue in the debug.log file within the wp-content folder.
If these steps do not resolve the issue or if the solution seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix,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. If the problem persists, please open a new support ticket.
