Problem: The client is experiencing issues with the WooCommerce add to cart functionality on their multilingual site using WPML. In English, the add to cart does not work, and some pages show a 404 error. Solution: 1. Update WooCommerce to the latest version and ensure the parent theme is also up-to-date. 2. Test the site with only WPML and WooCommerce plugins enabled to check for any plugin conflicts. 3. Increase the PHP memory limit by adding the following line to the wp-config.php file:
define('WP_MEMORY_LIMIT', '256M');
Place this line just before the comment that says /* That's all, stop editing! Happy publishing. */. 4. If the issue persists, consider providing temporary access (wp-admin and FTP) to a staging site for further investigation. 5. Always back up your database before making changes.
If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, we recommend opening a new support ticket.
