Working on my first decoupled site. Backend is handled by WordPress and lives on the subdomain admin.mydomain.com and the frontend lives at mydomain.com.

The first issue I saw with the headless approach, was that all permalinks referred to admin.mydomain.com. I wanted to change that so that the backend referenced to my frontend.

So I changed my config from:


which sorted my issue with the permalinks, but now I'm getting console errors on the WP dashboard because the plugins can't find the resources they need, for example ACF:

index.php:63 GET http://mydomain.test/app/plugins/advanced-custom-fields-pro/assets/css/acf-global.css?ver=5.8.4 net::ERR_NAME_NOT_RESOLVED

What would be the proper course of action to fix this?


My quick and dirty fix looks like this (please note that I use Roots Bedrock, so it differs from a vanilla WP install).

  1. In .env add this line WP_HOME_ADMIN='http://admin.mydomain.test'

  2. In application.php add this line, preferable just after where WP_HOME is defined: Config::define('WP_HOME_ADMIN', env('WP_HOME_ADMIN'));

  3. Somewhere after where CONTENT_DIR is defined, add this line: Config::define('WP_PLUGIN_URL', Config::get('WP_HOME_ADMIN') . Config::get('CONTENT_DIR') .'/plugins');
