We have been using the unknown traffic page to add our routers to a new NTA installation. We add the netflow config and our new SNMP community string to a router, wait 10-15 seconds, and the alert about unknown netflow traffic shows up at the top of any page after we refresh. When we click the link that takes us to the "Last 200 Unknown Traffic Events" page, the page is blank below the Clear Notifications and Refresh Events buttons. This just started. We've used this process to add about 80 routers without issue. This happens in IE 8, IE 9, and Chrome on Windows 7 32 and 64 bit, so it doesn't appear to be a client side problem. The alert part is working. We get the message indicating that there is unknown traffic, and clicking the link takes us to the right page, but the page is blank. I'll enclose a screenshot.
