Problem: The client is experiencing an issue where the translation of the Flexible Shipping plugin does not update when switching languages unless debug mode is enabled. This problem arises due to unwanted strings being registered for translation, which conflicts and prevents the string from appearing translated. Solution: 1. Change the Shipping Method Title in WooCommerce to the desired language. 2. Navigate to WPML > String Translation and delete all shipping method strings. 3. Clear the cart in the default language, add a product, and visit the cart page to register the correct string. 4. Add translations for these strings. 5. Switch to another language, update the cart by either increasing the product quantity or deleting an item to refresh the cache and see the translated string. If the issue persists, it's important to note that WPML cannot force refresh WooCommerce caches directly. You can clear WPML caches via WPML > Support > Troubleshooting, but updating the cart is necessary to see the correct translation.
