Understand development and production modes
Some applications can be configured in either “development” or “production” mode:
Production mode: File permissions and configuration settings are set with security and performance in mind. Installing certain plugins, themes and updates may require manual changes or installation of additional services like FTP.
TIP: This mode is recommended if the stack will be deployed on a public server.
If you install a module or stack and select production mode, these applications will request an FTP account in order to download their extensions. If you already have an FTP server on your machine, use this mode.
Development mode: File permissions and configuration settings are not optimal from a security standpoint but make it easy to install plugins, themes and updates for certain applications.
TIP: This mode is recommended for development purposes or for use on a private company network or intranet.
