We have posted a update to the Site Store Pro PHP shopping cart to address some minor compliance issues and bug fixes. This is a recommended update but not required. This interim patch addresses some issues with false positive XSS alerts on PCI compliance scans, an issue with the CMS where form emails were not sending correctly on specific configurations and an issue on the admin login where the Captcha was not working correctly. This patch can be applied to any Site Store Pro shopping cart (php) version including versions before and after the January 2015 API platform release and will not affect any design integration or customizations on the install. To upgrade, download the zip file from the link below and upload (copy) the folders inside it to your installation.  (/sitestorepro/ and /estore_admin/). Download the upgrade file here. If you have any questions about the upgrade process or need assistance, please email [email protected] or submit a priority support ticket.
