Aptivate

<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>
