I installed version 1.2.20, but the bug is still there.
You need to use __DIR__, otherwise it won’t work in most cases.
This is how you do it:
add_action(‘init’, function() {
require_once __DIR__ . ‘/get-token.php’;
require_once __DIR__ . ‘/get-tags.php’;
require_once __DIR__ . ‘/get-campaigns.php’;
require_once __DIR__ . ‘/get-workflows.php’;
require_once __DIR__ . ‘/contacts.php’;
require_once __DIR__ . ‘/get-custom-values.php’;
require_once __DIR__ . ‘/get-custom-fields.php’;
});
