Problem: After updating WPML from version 4.8.1 to 4.8.4, a critical error occurred causing the site to crash. The error was specifically an E_ERROR in /nas/content/live/oolie/wp-content/plugins/sitepress-multilingual-cms/vendor/wpml/wpml/src/Infrastructure/Dic.php with the message that the class "AurynInjector" was not found. Solution: We recommend updating WPML to the latest version, 4.8.5, to resolve this issue. You can find the latest version in your WPML account under My Account -> Downloads. Follow the instructions on that page to update WPML. Ensure to backup your database before proceeding with the update. If the 'Check for updates' button is not visible, you may need to manually check for updates in the Plugins → Add New Plugin → Commercial tab.
