Hi, it started 2 days ago, all pages remaining from the previous session and any new pages were blank.
Pages go to pending mode to get loaded but after about two seconds, pending stops by showing a blank page.
I've done update check, extension removal, browser default settings, uninstall and reinstall, none of them works. even opera help page doesn't show up.
Would appreciate suggestions to this matter. I was satisfied with Opera and its built-in features.
