How to Hide the WP Language Switcher on the Login Page

Introduction

The BuddyBoss Theme and Platform do not include a built-in option to hide the WordPress language switcher on the login page. Since this element is part of WordPress core functionality, hiding it requires a small custom code change that affects the login screen’s appearance.
This guide explains how to hide the WP language switcher on the login page using a simple function added to your active theme.

Custom Workaround

Before proceeding, make sure you have a complete site backup.

1. Go to Appearance > Theme Editor in your WordPress admin dashboard.
   
2. Under Select theme to edit, choose your active theme (preferably a BuddyBoss Child Theme), then click Select.
   
3. From the Theme Files list, open Theme Functions (functions.php).
   
4. Add the following code just before the closing PHP tag (?>):
   

add_filter( 'login_display_language_dropdown', '__return_false' );

5. Click Update File to save the changes.
   

After saving, the language dropdown will no longer appear on the WordPress login screen.

Note: Modifications are typically considered custom work, but we are making an exception in this case. Please review the BuddyBoss Support Policy.

Troubleshooting and FAQs

Q: The language switcher is still visible.
A: Ensure the code is added to your child theme’s functions.php file and not the parent theme. Clear any caching plugins and refresh the login page.

Q: Can I show the language switcher again in the future?
A: Yes. Simply remove the code or comment it out:

// add_filter( ‘login_display_language_dropdown’, ‘__return_false’ );

Q: Will this affect the WordPress admin language selection?
A: No. This only hides the language dropdown on the login screen. Admin users can still change their language from their profile settings in the dashboard.
