Interact is fully compatible with OutSite-In.
In order to take your Interact web site on CD or simply offline, we recommend you to:
Modify the "\local\config.inc.php" file by editing your offline files directory:
Find the line starting with:
$CONFIG['FULL_URL'] = ...
and change it to:
$CONFIG['FULL_URL'] = 'http://'.$_SERVER["HTTP_HOST"];
Find the line starting with:
$CONFIG['DBSERVER'] = ...
and change it to:
$CONFIG['DBSERVER'] = 'localhost';
