We have made a fix of the 'payment.php' file after release 3.2 has been issued.
Description.
The bug concerned the payment systems which do not have an 'Advanced' flag and when a user clicks 'Pay for your Order' and have an SSL option for the 'payment details pages' he was not redirected to a secure host.
Solution.
Please, download an updated version of the 'payment.php' file from here:
http://www.viart.com/downloads/payment-3.2.zip
Then extract the file into the root 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.
