Lets users change their administration language to English
This plugin lets users change their administration language to native English (en_US locale).
This is useful during site development and for people more accustomed to the english administration panel, even if your site is in another language. (The frontend will still use the native language.)
This plugin is developer friendly and small (~100 lines of code). Check the FAQ for customization examples.
Once you have installed and activated the plugin, navigate to any admin page and check the top admin bar. A button will display your current locale. If you click on it, the admin will change to English locale (en_US). To switch back, press the button again.
