Feature since v1.16.0

# Internationalization (i18n)

The entire admin interface and all server-side strings are translatable — English by default, with Polish, Simplified Chinese, and Dutch bundled, plus WPML and Polylang compatibility.

The plugin is fully internationalized: every admin screen, dialog, and inline message, plus all server-side strings, are wrapped for translation. English is the default (source) language; Polish (pl\_PL), Simplified Chinese (zh\_CN), and Dutch (nl\_NL) translations ship bundled and load automatically when WordPress is set to a matching site or user locale. The plugin is compatible with WPML and Polylang String Translation, and free locales can also be contributed through translate.wordpress.org.

## Bundled languages

English is the default (source) language. Polish (`pl_PL`), Simplified Chinese (`zh_CN`), and Dutch (`nl_NL`) translations ship bundled with the plugin. WordPress loads the matching set automatically based on the site or per-user locale — no configuration required.

## Translation compatibility

Works with WordPress native locale switching, WPML, and Polylang String Translation. Community translations for the free plugin can be contributed through translate.wordpress.org.

## Adding a language

Drop a locale `.po`/`.mo`/`.json` set into the plugin's `languages/` directory. The `.pot` template covers all PHP and JavaScript strings — the Vue SPA strings are extracted from source, since `wp i18n make-pot` cannot read `.vue` files.

## Reliable JS translation loading

The admin bundle uses a stable, hash-free filename with handle-based script-translation loading, so JavaScript (Vue SPA) translations resolve reliably across plugin updates.
