Problem:
The client installed WPML on their website and experienced significant performance issues. The site became slow and unresponsive, and disabling WPML restored normal performance. The issues persisted despite updating plugins and themes, and the WooCommerce Force Default Variant plugin and the theme Savoy were suspected to be contributing to the problem.
Solution:
We recommended the client to update all outdated functionalities and provided a checklist to enhance site performance, available at https://wpml.org/forums/topic/how-can-i-improve-performance-of-a-slow-site/#post-15350474. We escalated the issue to our 2nd tier support for deeper analysis. It was found that the WooCommerce Force Default Variant plugin and the nm_template_loop_attributes function in the Savoy theme were causing the issues. We advised against using the WooCommerce Force Default Variant plugin and recommended upgrading WPML plugins to the latest version for performance improvements.

If this solution does not resolve your issue or seems outdated, please check related known issues at https://wpml.org/known-issues/, verify the version of the permanent fix, and confirm that you have installed the latest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. If problems persist, we highly recommend opening a new support ticket at WPML support forum.
