Problem:
I am having an issue with slow product editing on my WooCommerce website with two languages. When editing products, the administration becomes very slow, and editing 5 or 6 products can potentially saturate the server, leading to website crashes (Error 503 or Error 500). After deactivating all plugins, it was identified that the "sitepress-multilingual-cms" and "woocommerce-multilingual" plugins are causing slowdowns due to numerous admin-ajax requests, specifically related to WPML.
Solution:
1. Increase the WordPress memory limit to a minimum of 128Mb by adding the following code to the wp-config.php file:
define('WP_MEMORY_LIMIT', '512M');
2. After increasing the memory limit, go to Plugins -> Add New -> 'Commercial' tab -> Update the WPML plugins.
3. If the issue persists, contact your hosting providers and ask them to increase the memory limit on the server-side.
