Xaraya is fully compatible with OutSite-In.
In order to take your Xaraya web site on CD or simply offline, we recommend you to:
Modify the "\var\config.system.php" file by editing your offline files directory:
Find the line starting with:
$systemConfiguration['DB.Host'] =...
and change it to:
$systemConfiguration['DB.Host'] = 'localhost';
(tested with Xaraya 1.2.2)
