Setting Up Web Browser Security Policy
Civic Platform generates receipts with a browser pop-up feature when users process a payment in a cashier session. You cannot view or print receipts unless you set Civic Platform as a trusted site, enable Active X features and scripting, and disable pop-up blockers from Microsoft Internet Explorer (IE), Google Toolbar, and Yahoo Toolbar.
Follow the instructions in Trusted Sites and Zones Settings to set up the browser security policy, and then restart your browser.
