Hi Dave. Maybe you can help me with this problem. Whenever I try to go on a site that requires secure log-in, eg. bank, ebay etc. I get a security warning pop-up saying there is a problem with the sites security certificate. It says “the security certificate has expired or is not yet valid” and gives me options to continue yes/no or view certificate. I am operating Windows ME and IE 6, all updated and I also run AVG free anti-virus and spybot regularly. I have searched the web for answers to this and also asked several PPL including my bank’s IT helpline. I have done everything suggested but still get the warning!
After thinking about this for a while, I wasn’t sure that I had any particularly great solution to propose. My standard response would be to check the security preferences of the Web browser and to try visiting one or more of the sites using a different browser like Firefox.
In a private dialog, however, I was pleased to hear that the chap who sent in this question figured out the problem on his own, and it’s a beauty:
Dave, just so you know, I’ve figured out my problem with the expired or not yet valid security certificates: the date on my computer was set wrong and it thought I was years in the past! Once I fixed the date and time, all of these problems vanished.
This is a simple solution to a vexing problem and, as Sherlock Holmes shared with his colleague Dr. Watson, once you eliminate all other possibilities, what’s left, however improbable, must be the solution.
