Brief.
We have made a fix of the 'admin_upgrade.php' file after release 3.2 has been issued.
 
Description.
The field 'item_notify' was missing in the file and thus a DB error occurred after the upgrade.
 
Solution.
Please download an updated version of the file from here:
http://www.viart.com/downloads/admin_upgrade-3.2.zip
Then extract the 'admin_upgrade.php' file into the 'admin' folder of your shop replacing an existing one.
Don't forget to make a backup copy of the current file in case something goes wrong.
