On an upgrade from mambo-phpShop, the VirtueMart installer won recognise my existing tables! What to do now?
Sometimes the tables beginning with jos_pshop_ or mos_pshop_ are not found. Before you click on “Install sample data” or “Go directly to the shop” you can just type in this URL in the addess bar of your browser: index2.php?option=com_virtuemart&install_type=update12pl3 After that the upgrade procedure begins!
