This plugin helps you to declutter your WordPress login screen by removing the language switcher which has been <a href="https://make.wordpress.org/core/2021/12/20/introducing-new-language-switcher-on-the-login-screen-in-wp-5-9/" rel="nofollow ugc">introduced in WordPress 5.9</a>.
Removing the dropdown makes sense when you only have one additional language installed and don’t intend to change back to English for example. In this case you can simply install and activate the plugin. There are no futher settings.
<h3>What does this plugin do?</h3>
The plugin uses the default <a href="https://developer.wordpress.org/plugins/hooks/" rel="nofollow ugc">WordPress Hooks API</a> and disables the language selector with the following one-liner:
<pre><code>add_filter( 'login_display_language_dropdown', '__return_false' );
</code></pre>

Disable Login Language Switcher

Does what it says on the tin.

Removes the language dropdown from the login screen.

On posts where comments are closed, the plugin will remove the text ‘Comments are closed.’ The plugin supports any languages/text domain, and will remove the text from themes and plugins.
Prerequisite: Since the plugin is <a href="https://codex.wordpress.org/Plugin_API/Filter_Reference/gettext" rel="nofollow ugc">filtering gettext</a>, your theme/plugin must be <a href="http://wp.smashingmagazine.com/2011/12/29/internationalizing-localizing-wordpress-theme/" rel="nofollow ugc">localized</a>.
