Whenever I sign in, it looks like nothing's really updating. I have to scroll down a bit on my feed to finally get to something older. It only shows one post within the last 9 hours. I checked with Firefox, and everything seemed fine. It would show replies to one of my friend's posts while Opera wouldn't. Nor would it let me comment. Not sure if there's a connection to me clearing all of my browser data. The problem only seems to be with Facebook.
Try it in a Private Window. Did that fix it?
Sorry. By the time I woke up it was acting normally again. I hadn't closed Opera at all, so maybe I was on Facebook's end?
Just now was the first time I've ever opened a private window. Not sure what I'd really use that for.
