How can you have your WordPress admin in English language and the frontend in another language? Maybe your local language? Which plugin to use?
The fact is that the majority of documentation about WordPress (WP) is in English language. It is easier to seek support when your WordPress back end (administration) is displayed in English language.
So how can you do that?
The answer is the English WordPress Admin plugin.
By installing and activating this plugin, you will operate the WP dashboard in the English language, what ever your frontend language is.
All messages, warnings, interface will be in the English language.
I quote from plugin’s description page:
“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 front end / backend AJAX requests.
If you are using this plugin with Advanced Custom Fields, please move the english-wp-admin.php file to the /wp-content/mu-plugins/ folder
(create it if it does not exist). This is an ACF limitation.”
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.
Free. This is a free WP plugin.
