Internet Explorer 7 problem

[jivebunny]

When I try to access a web page or site with HTTPS prefix I get an error message - number 12169 and narrative "The supplied certificate is invalid". Everything was OK last week - this problem just appeared at the weekend. Can anyone suggest a fix for this?

Well could well be a problem there side,
12169 doesnt really tell you much ,

can you post the url of the site?

its doubtfull IE 7 is cause as it has more certs built in than the older version ie 5 or 6, the web site you are trying to reach is responisble for making sure there certificates are correct and uptodate. can you get to same site on any other pc (work friend etc)

do you have a firewall? speak to the company that provides you with broadband and the routher they gave you
