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 fully compatible with WooCommerce and can correctly identify and translate frontend / backend AJAX requests. 
If you are using this plugin with Advanced Custom Fields, please move the as-english-wp-admin.php file to the /wp-content/mu-plugins/ folder 
(create it if it does not exist). This is an ACF limitation.
This plugin is developer friendly and small (~200 lines of code). Check the FAQ for customization examples.
Usage

Once you have installed and activated the plugin, navigate to any admin page and check the top admin bar. A button will
