I upgraded my shop but now I see a free message "Ecommerce Solutions by ViArt Ltd" at the bottom.

To activate your license on version 4.0 you need to go to activation page where insert your serial number and then select the option to generate a license file for version 4.0 like on this screenshot. Afterwords upload "license.php" file to your shop's 'includes' folder in Binary mode.

I have upgraded my shop and regenerated a license but now I see a message "Your license has been expired".

It means your license free updates period has expired and you need to buy Updates Extension for your type of license.

This error indicates that you are trying to upgrade from an old version which has different database structure. In this case we recommend to order Upgrade Service or you can try to perform upgrade yourself by doing the following changes:

• disable admin_security check in all upgrade scripts;
• comment these includes in admin_upgrade.php:
  include_once("./admin_header.php");
  include_once("./admin_footer.php");

I've been upgrading my shop and custom mods on the test copy for awhile. How can I safely upgrade my Live site?

There are two ways of how you can proceed:

• 1) upgrade Live site:
• upload all files from test copy over your Live files;
• change the var_definition.php file to link to the Live database;
• click 'System Upgrade' in admin panel;
• apply dump of CMS tables from test copy to the Live site (to save layout changes if you made any).
• 2) use test copy as a Live site:
• make export of orders, users and products* information from Live site.
  *Note: we do not recommend to add any new products or change current ones during upgrade period because export/import of products doesn't preserve all product information such as options, subcomponents etc.
• delete your Live site (making a backup beforehand) and upload the test copy in its place;
• import orders, users and products information.
