For some reason, I can't enter www.google.com, it says this
but somehow I can enter www.google.com.tr, which the 'tr' stands for Turkey, and it's the country I am living.
So because of this problem, I tried to change it in settings, first tried to edit default google search, but I couldn't. Then tried to create a custom search engine and set it as default, but as you know I am not able to do that for some security reasons according to Opera itself.
I need some guidance to get over this problem somehow, any response is appreciated.
