I've been having this problem for a while and I have no idea what might be causing it.
Everytime I try to go to a HTTPS (note the S, for secure) site, it says that the page cannot be displayed. I don't think it's my browser settings or
my firewall.
Help would be much appreciated. If you need more info, I'll gladly post it.
You'll see a checkbox. Uncheck it or check it, then past the site in the list. It should fix your problem. Anyway, if it's checked, you can only
past a secured site ( https ).
And if doesn't fix your problem, try this link : Link
