I have installed Drupal through quick app installation, but I keep getting the below error.
Redirects to external URLs are not allowed by default, use \Drupal\Core\Routing\TrustedRedirectResponse for it.
yeah. that worked like a charm. Only issue I had was I couldn’t modify settings.php for that user later. I don’t know how widespread that is. Changing the file via nano and ssh worked just fine.
