Problem: The client manually installed the WPML Multilingual & Multicurrency for WooCommerce plugin, which is updated to version 5.5.3. However, the plugin appears as 'Not installed' in WPML and the WordPress support panel, causing issues with product variation translations and missing WPML features like the 'Multilingual e-commerce' menu. Solution: We recommend deactivating all plugins except for WPML to check for conflicts. This should be done in small batches, about 10 at a time, to ensure that any settings causing the issue are reset. After deactivating and reactivating, the variations should appear as expected. It is crucial to always have a backup before performing these steps. Additionally, always clear all caches after publishing a product and its translations to prevent similar issues.
