      I also have this problem with invalid certificate for Twitter. I'm running Opera 22.0.1471.70. I googled this and found that the problem is for a "Chrome client" running on Windows XP SP2. The recommended solution is to upgrade to SP3. Twitter is using a certificate that is not supported on SP2.

      As Twitter is working with Opera 12.17.1863 and SP2, is it possible to remove the troublesome certificate in Opera 22?

        This problem could be caused by the date on your computer set wrong. Check the date on your computer. Browser certificates have a start date and an end date. If your computer date is set to far of one way or the other, that can cause this problem.

          Ive had this exact same problem with no solutions for the last several months. Running XP with latest service packs. Read the same recommendations about computer time/date, Antivirus SSL, both of which did not solve the problem.

          As of yet there is no working solution for this issue.

          Our company has been instructed to not use Opera. I wish this issue would be resolved but thus far I dont see any actual solutions just a few ideas that dont work.

                I've only had it once (I accepted the certificate), but I got that error when visiting the link below.

                  The error popups about files.myopera.com occures because someone had inserted some picture in a posting from a old Opera domain myopera.com, which does not exist anymore.

                    Ah thank you (it was of course files.myopera.com generating the error, not files.opera.com as I wrongly said!)
                    That explains it.
                    🙂
