<p>This plugin, which requires <a href="https://wordpress.org/plugins/polylang/" rel="ugc">polylang</a><br />
provides the means to include posts that have no translation in the current<br />
language on pages of posts.</p>
<h4>Usage</h4>
<p>Multilingual Polylang provides two public functions:</p>
<p>The function <code>MultilingualPolylang::get_query()</code> returns a <code>WP_Query</code> object with posts from<br />
all languages but where there is a translated post, only the post in the current<br />
language will be included</p>
<p>The function <code>MultilingualPolylang::get_permalink()</code> can be used as a drop-in replacement to<br />
    get_permalink(). This will replace the language in a post URL so that a post<br />
can be viewed in a language different to that of the rest of the interface.</p>

<h4>Closing announcement</h4>
<p>It has been a while since we are helping to translate websites in multiple languages and we appreciate your confidence in the plugin for that. Unfortunatelly, we don’t have capacity for maintining the plugin and providing support. We are not offering support any more, this plugin is outdated and it might not work in your website.</p>
<p>Due to the plugin could not work in current and future WordPress versions and new bugs found could not be solved, we encourage users to test and make changes to use <a href="https://wordpress.org/plugins/search.php?q=language+translation" rel="ugc">another translation plugin</a>.</p>
<p>Finally, our apologizes by any problem we could cause with this decision.</p>

<p>User Language Switch is a WordPress multilingual plugin that you can use to build multilingual websites. It displays flags to visitors that your users can use to browse your website in different languages. If you prefer, you can deactivate flags and user shortcodes and functions to create your own language switch.</p>
<p>Admin users can set default language for your website and registered users can set language they want to see your website by default. User Language Switch allows to set language for back-end and front-end independently.</p>
<p>When content is linked, a language prefix is added in URLs of content in secondary languages. The plugin always redirect to URLs with language prefix for content in secondary language, in this way there are no different URLs pointing to the same content and hurting your SEO. This plugin is compatible with SEO plugins like Yoast SEO.</p>

User Language Switch

The Plugin is very preferable for any languages. But have no option for slider translation (like revslider/layerslider). Hope it will be able in future.
