The screen shot mentions the dates on the cert.. which is why I rule out the name and/or missing root causes..This could be caused by an invalid or missing root certificate, the certificate being expired, or the name of the certificate does not match the site.
O.K. I use Wamu all the time and it has never done that to me. I have used IE, Firefox, and Mozilla, and Opera on three different computers. Now if the BIOS bat died and the dates are of 2005 there could be a conflict since this is 2007. Change out the bat and clear the CMOS and start fresh.my parents have been getting this screen in IE and ff...any ideas???
