As I said in my previous post we'll need more precision, did you upgraded your Hikashop version as it's said in the
documentation
?
If you want to install the latest version of HikaShop or upgrade to any commercial version, the upgrade process is as easy as the install one!
You don't have to uninstall HikaShop. Simply proceed as explained above and install the new package via the Joomla "Install/Uninstall" screen and HikaShop will be upgraded without loosing any of your data.
PS: You should create one thread per issues
.
