Problem: The client is experiencing a critical error due to a high number of autoloaded options in their WordPress site, which is affecting site performance. They need guidance on reducing these options, creating a custom XML configuration file for WPML, and whether installing an object caching plugin would help. Solution: To reduce the number of autoloaded options, ensure that the 'autoload' setting for the 'wpml-tm-custom-xml' option is set to 'off'. If it's not, you can adjust this manually. If a wpml-config.xml file already exists on your site, you can manage it under WPML -> Settings -> Custom XML Configuration (tab). If you're unsure whether the file exists, it's safer to leave it as is. For detailed instructions on creating a wpml-config.xml file, visit https://wpml.org/documentation/support/language-configuration-files/. Regarding the installation of an object caching plugin like Redis or Varnish, while it's not directly related to the autoload issue, it is generally recommended to enhance site performance.
