A simple, powerful, and user-friendly plugin that adds multilingual support to your WordPress multisite installation, whether using multiple subdomains or folders. Multisite Language Switcher allows you to effortlessly manage translations for posts, pages, custom post types, categories, tags, and custom taxonomies.
The plugin uses flag icons from FamFamFam. Thanks to Mark James for his great work. In addition, I would like to thank Jürgen Mayer for creating the plugin’s banner.
Please, don’t forget to rate this plugin! 🙂

You can translate this plugin on translate.wordpress.org, or if you prefer and have created your language pack, or have an update of an existing one, you can send me your Gettext PO and MO so that I can
bundle it into the Multisite Language Switcher. You can download the latest POT file
from here.
- Use the WordPress admin to install the plugin from there or
- Download the plugin and uncompress it with your preferred unzip programme and copy the entire directory in the plugin directory of your WordPress blog (/wp-content/plugins)
- Activate the plugin in your plugin administration page (by the network administrator on all the blogs or by the blog administrator for each particular blog).
- After activation, configure the plugin once in each blog under
Settings->Multisite Language Switcher
Now you can:
- Connect your translated pages and posts in
Posts->EditorPages->Edit - Connect your translated categories and tags in
Posts->CategoriesorPosts->Tags - connect your Custom Post Types and Custom Taxonomies across languages
- create a missing translation in one step – straight from the editor metabox, or from the
Add from Translationsubmenu, which lists everything that is not translated yet and can create translations in bulk (Quick Create, new in 3.0) - use the widget, the Gutenberg block, the shortcode [sc_msls] and/or a content_filter which displays a hint to the user if a translation is available
- you can find also a shortcode for the widget [sc_msls_widget]
- optionally you can place the code
<?php if ( function_exists( 'msls_the_switcher' ) ) msls_the_switcher(); ?>directly in your theme files
Review the Multisite Language Switcher Website for more information.
Developers will find the API functions, every action and filter, and a set of integration
snippets in the developer documentation.
You might read first WordPress in your language.
You can choose the language of the dashboard in the settings of your user profile.
It’s up to you – of course. But yes, if you want to use the Multisite Language Switcher.
The Multisite Language Switcher does not redirect the users automatically. I’m not sure if the plugin should do that.
Please check the add-on MslsMenu out.
Please check the add-on MslsSelect out.
Yes, you should use the WordPress API function get_locale() but you could also use code like that
$blog = msls_blog_collection()->get_current_blog();
$language = $blog->get_language();
The class behind it moved to lloc\Msls\Blog\Collection in version 3.0.0. The old name
lloc\Msls\MslsBlogCollection still resolves, so existing code keeps working.
Please visit the MSLS website or use the WordPress support forum for more information.
Changelog
3.0.3
- Fixed: on PHP 7.4 the plugin’s dependencies could not be installed, because one of them required PHP 8. MSLS supports PHP 7.4 again, as documented.
3.0.2
- Fixed: with more than 100 users on a blog, opening the settings page raised a PHP notice that ended up in the error log (and in services such as Sentry). The truncated user list is now reported as a hint below the “Reference user” dropdown instead.
- Changed: MSLS no longer runs
count_users()to detect the truncation, which removes a costly query from the settings page on blogs with many users.
3.0.1
- Fixed: 3.0.0 could not be published on WordPress.org
- The plugin code is identical to 3.0.0.
3.0.0
- New: Quick Create – create the translated post straight from the editor metabox, or pick a source post on the new
Add from Translationsubmenu (single and bulk). Backed by a REST endpoint and switchable in the settings. - New:
msls_quick_create_capabilitylets integrations override the Quick Create permission checks. Additional filters cover the post data, the inserted post, the REST response, the untranslated-posts list and the mapped taxonomy terms. - New: filter hooks for the AJAX suggest results of the post and term metaboxes.
- New: a developer reference in
docs/– public API, every hook, integration snippets and the Playwright setup. - Changed: the
lloc\Msls\namespace is split into per-concern sub-namespaces. Every pre-3.0 class name (MslsOptions,MslsLink,MslsOutput, …) keeps working through a backwards-compatibility alias, so add-ons and custom code do not need changes. - Changed: the public helper functions moved to
includes/api.php, and the$attrargument ofmsls_get_switcher()is now optional. - Fixed: add-ons such as MslsMenu and MslsSelect could be silently disabled because the plugin registered its classes too late. Aliases and API functions are now available the moment the plugin file is loaded.
- Fixed: authorization is checked on the destination post during content import, and the ContentImporter permission and post type checks were corrected.
- Fixed: no
home_url()fallback for taxonomy and query archives anymore. - Fixed: broken links on the page for the latest posts.
- Fixed: several issues in the blog collection.
- Internal: strict typing throughout, PHPStan level 8 clean,
ABSPATHguards, Plugin Check and PHPCS findings addressed, a wp-env based local multisite and a Playwright end-to-end suite.
2.10.1
- Fixed: deprecated function warning pointed to a non-existent function.
- Documentation: README.md code snippets reflect the new function names.
2.10.0
- New: prefixed public helper functions (
msls_get_*,msls_the_switcher) with deprecation shims for the legacy names. - New: action hook names are exposed as constants for safer programmatic use.
- Accessibility:
aria-current="page"on the active language link. - Fixed: path-related issue affecting asset/loader resolution.
