Brief.
We have slightly modified the admin_item_categories.php script after release 3.3.2 has been issued
 
Description.
The below SQL error may appear while clicking on the categories link under a product (for those who use PostgreSQL):
 
PostgreSQL Error Message: ERROR: column "c.category_order" must appear in the GROUP BY clause or be used in an aggregate function
Session halted.
 
Solution.
Please download an updated version of the files from here:
http://www.viart.com/downloads/admin_item_categories-3.3.2.zip
Then extract the above mentioned file into the 'admin' folder of your shop replacing an existing one. Don't forget to make a backup copy of the current files in case something goes wrong.
