Allows backend users to set the language displayed in the back-end and front-end of your site. It also allows to translate pages and posts.
User Language Switch allows each backend user to set the language displayed in the back-end and front-end of the site. ULS also allows to associate the original version and the translation of pages, posts and custom post types through custom fields in an easy and friendly way. You can easily create the language links by adding the [uls-language-selector] shortcode. The available languages are taken from the current theme and the wordpress installation.
