What is Auth code and where can I find it?
 

For security reasons, we added Auth code into install.php script. When the installation script detects that X-cart is already installed on your host it will not allow you to proceed without entering the Auth code.

To protect your work, we recommend either deleting script install.php, or changing default Auth code. But it is better to keep install.php since you may need to install different skin sets (X-cart comes with several skin sets).

You will find the Auth code in [xcart_dir]/include/install.php file:

# Put access code here
# A person who do not know the auth code can not access the installations script
#
$installation_auth_code =
You may change the auth_code at any moment. Also the code is displayed in the admin back-end, on the 'Summary' page.
