We are XStore theme developers and we are responsible for theme settings only. We can just suggest plugins that may help you to implement some additional features but we are not responsible for these plugins. Contact plugin author to get a clear answer about all the available options and compatibility with the latest WP version.
We are sore the WPML plugin is compatible with the latest WP version because it’s paid plugin and plugin developers release the regular updates. But can tell you nothing about free plugins.
