Then, when you start Opera, it'll be like you just installed it. If things are still messed up with Opera, check the date, time, time zone and daylight savings time settings on your computer to make sure they're all correct.
Also, if you're using CCleaner or an app like it, make sure it's not deleting Opera's cookies.
Also, check to make sure your anti-virus isn't messing with Opera.
I actually installed first Opera a few days ago on my new computer, and the issue was there right away.
I don't use CCcleaner.
Checked Anti Virus and Firewall nothing should mess with Opera and the issue's still there.
