Configuration File

The Nestor configuration file - vce-config.php – is found in the root directory of your installation. This file defines and assigns values to a variety of constants that will allow you to fine-tune the workings of your installation.

Manually Configured Settings

Installer Defined Settings

During installation, some key settings are written to the Nestor configuration file. Many system issues can be caused by the wrong settings, so be careful about changing any of these key settings.

Setting Name	Description	Origin
DB_HOST	Hostname of your webserver, commonly “localhost”	Written by installer from value provided by end user
DB_NAME	The name of the database used to store application info	Written by installer from value provided by end user
DB_PASSWORD	database password	Written by installer from value provided by end user

SITE_KEY	Site key used by application for encryption – do not change this after install or your site will stop working.

In that case you would copy in the Site Key that is needed to decrypt the current data.	Generated and written by the installer
