File permissions after install
Writable storage and secure config.
Required writable
storage/logs/storage/cache/assets/uploads/
Config lockdown
After install completes, config/config.php should not be world-writable. Remove write permission from web user if your installer left it open.
Troubleshooting
If uploads fail silently, check PHP error log and folder ownership — shared hosts often need 755 on folders and 644 on files.
