"Safari attempted to access a secure website..." after 10.8.2
I upgraded to 10.8.2 this afternoon and now my son's parental controled account is broken. Whenever he tries to access a web page via Safari (or Chrome) he gets a message stating "Safari attempted to access a secure website..." I haven't changed anything on his account - it worked fine before the upgrade, so I assume 10.8.2 caused the problem.
I do have Parental Controls on his account, but web browsing is set to Unlimitied Access.
Please Help!
