Problem: The client needed to remove the Spanish language from a WordPress multisite and encountered issues where the deletion process would halt due to problems with WooCommerce product variations and database errors. Solution: We recommended the following steps: 1. Create a complete backup of the site. 2. Navigate to WPML -> Languages -> Site Languages, click on 'Add / Remove Languages', deselect Spanish, and save the changes. 3. If the issue persists, deactivate all WPML plugins, reactivate them, clear any existing caches, and check again. 4. Enable WordPress debug mode by following the guide at https://developer.wordpress.org/advanced-administration/debug/debug-wordpress/ and share the fatal error from the debug.log file. 5. If necessary, apply a specific workaround by modifying the plugin code at sitepress-multilingual-cms/classes/post-translation/endpoints/DeleteTranslatedContentOfLanguages.php.
