      I updated Opera on 22 March.
      After that, following error occurs on some web pages.
      It's too difficult for me..
      Please help!

      SSL Error:
      You connection is not private
      You attempted to reach www.google.co.jp, but the server
      presented a certificate signed using a weak signature algorithm
      (such as SHA-1). This means that the security credentials the server
      presented could have been forged, and the server may not be the
      server you expected (you may be communicating with an attacker.)

      You cannot proceed because the website operator has requested
      heightened security for this domain.

      Invalid certificate:
      Opera cannot verify the identity of the server
      "****(some page)", due to a certificate problem. The
      server could be trying to trick you. Would you like to
      continue to the server.

        I had no problems accessing that page.

        Do you use any anti-virus or security software? What about extensions?

          I installed Opera(Linux 64) just recently. And I strangely got the very same problem with Google and Youtube(But not with Facebook or spiegel.de). Obviously I had no extensions installed. I do not have this problem with Firefox or Konqueror.

            This is the Opera for Windows forum. For issues with Opera in Linux please use the Opera for *nix forum.

              I solved it myself. Thanks guys.

              1. This problem does not occur in Safe Boot + Network.

              2. I checked the event viewer.
                After updating, operaautoupdate.exe outputs error.

              3. I checked operaautoupdate.log
                Failed to resolve proxy auto config for https://autoupdate.geo.opera.com/ Err: 12180

              4. Recently updated are Adobe, VirtualBox, WindowsUpdate.

              So, I tried the following things.

              Organize services and startups.

              Then this problem was solved.
              (Reference: msconfig.exe)

              (I checked antivirus software at the beginning, but it seems not to be the cause of the problem.)
