Disable Login Language Selector Wordpress Plugin - Rating, Reviews, Demo & Download
Plugin Description
WordPress 5.9 added a new language selector to let users switch language on the login screen, however, if you already have a language switcher in place via your own code or another plugin then this plugin provides a quick and easy way to remove the Language selector that appears on the login screen if you have more than just one language enabled on your WordPress installation.
It is a very simple plugin which is provided for ease of use, but you can also achieve the same effect by adding the following line of code to the functions.php
file in your theme:
add_filter( 'login_display_language_dropdown', '__return_false' );
