Problem: The client is experiencing high CPU utilization and slow queries on their website when WooCommerce is activated along with WPML. Solution: We recommend the following steps to address the issue: 1. Ensure all WPML components are up to date by going to Plugins -> Add New Plugin, clicking on the Commercial tab, and then clicking the Check for updates button. Install any available updates for WPML Multilingual CMS, WPML SEO, Advanced Custom Fields Multilingual, and Ninja Forms Multilingual. 2. If updating does not resolve the issue, follow these troubleshooting steps: - Create a full site backup or a staging site with a copy of the production site. - Flush any cache memory. - Update all outdated plugins and themes, especially the WPML plugins. - Deactivate all plugins, including WPML ones, and activate a default WordPress theme like Twenty Twenty. - Reactivate the WPML plugins, WooCommerce, and WCML. If the issue disappears, reactivate the theme and then other plugins one by one to identify the problematic plugin.
