WordPress Language is a free plugin that lets you easily localize single-language WordPress sites.
Instead of having to download .mo files and edit wp-config.php to set the WPLANG variable, this plugin does it all for you.
Choose the language from within the WordPress admin and you’re ready.
WordPress Language will look for the best available translation for your language, download and install it. It sets the correct locale and everything appears in the right language.
Frequently Asked Questions
Does WordPress Language translate my content?
WordPress Language downloads and installs translation for texts in WordPress itself, not for your own content.
What languages can it switch to?
The list of language is dynamic, coming from an online index. You’ll find every language to which WordPress is localized. It’s a pretty long list and still growing.
How can I run a site in multiple languages?
If you need to run a site in one language, other than English, this is your solution. For multilingual sites, look at WPML.
