@leocg I can report that MANY sites have chosen to ask me to login again, and when I do the site will allow me in, the next time I go there, all is perfect. Other times not. For instance I had to reset my password on one, even though I entered the correct data. Others just make me login even if I had used the "remember me" box ticked previously. There is definitely something going on wherein many sites do not recognize my new Opera as me, as if some cookies had been deleted.
If this was jut one site, I wouldn't have posted, but this is happening at MANY, but not ALL.
Let me give you and example, I logged in toe a site I use, and instead of logging me in, it asked me to do one of those visual picture things, (click on all the photos that has an street sign in it, etc etc), as if it did not recognize my browser.
