Brief.
We have slightly modified the following scripts after release 3.3.2 has been issued:
block_basket_recommended.php
block_offers.php
block_product_details.php
block_products_latest. php
block_products_list.php
block_products_recommended.php
block_products_related.php
block_products_related_ purchase.php
block_products_top_sellers.php
 
Description.
When adding a product to be shown as a special offer with different prices depending of the login types products can duplicate.
 
Solution.
We recommend to download an updated version of the files from here: http://www.viart.com/downloads/items_prices_fix-3.3.2.zip
Then extract the above mentioned files into the 'blocks' folder of your shop replacing existing ones. Don't forget to make backup copies of the current files in case something goes wrong.
