In /includes/version.php look for:
Quote:
/** @var string Whether site is a production = 1 or demo site = 0 */
var $SITE = 1;
/** @var string Whether site has restricted functionality mostly used for demo sites: 0 is default */
var $RESTRICT = 0;
For a demo site it is advised to following:
Quote:
/** @var string Whether site is a production = 1 or demo site = 0 */
var $SITE = 0;
/** @var string Whether site has restricted functionality mostly used for demo sites: 0 is default */
var $RESTRICT = 1;
$SITE = 0
Allows multiple user logins with only one account. By default Joomla! allows only one active session per account as a security feature.
$RESTRICT = 1
Disables those logging in, both frontend and backend from changing user details - like password and username
These were added as we needed them to aid the management of the official demo site
http://demo.joomla.org You should also make all files and folders nonwriteable - especially the configuration.php file.
Also recommend you setup an automatic cron job that refreshes the database at a set interval (in our case 60mins) from a db script.
These are what we do for our official demo site
