Problem: The client reported a significant performance decrease on their website's backend after using WPML with the Divi theme, especially when adding new products. The database size had grown to 3.5GB for 4,000 products, resulting in over 10 seconds of wait time for backend operations. Solution: 1. We suggested testing with minimal settings, which includes only WPML plugins active with a default theme, to rule out compatibility issues. We also recommended testing with only WPML active with the Divi theme. 2. On the client's site, we performed the following steps: - Ran the synchronization of product category hierarchies as prompted by the admin dashboard banner. - Checked WooCommerce Multilingual & Multi-Currency status for configuration issues and adjusted the WPML settings for
product_variation
, which cannot be set to "fallback". - Advised the client to update all plugins, including WooCommerce, WCML, WPML String Translation, and the Divi Theme. - Noted a long load time when opening the 'Add new' product page and a related notification from the Query Monitor plugin concerning the Autoptimize plugin. - Discovered that deactivating Autoptimize reduced the product edit screen load time to 3 seconds, and upon reactivation, the previous load time issue did not recur, indicating the problem was resolved and not related to WPML.
