Sage Pay is going to upgrade their systems on Saturday 17 April 2010 at 22:00 , you can read the official announcement here


Our Magento extensiosn (either paid or free) are not affected by this system upgrade. However, if you are running our Sage Pay Server Pro extension you have to check with your hosting provider if there’s any firewall rule that would prevent Sage Pay from reaching your server.


If you have any doubt please contact us, we’ll be happy to help you.
