The last time I logged in on Stack Overflow I had more than 15 reputation and I had some badges like Suffrage, Supporter, Citizen Patrol, Teacher. I had posted a question as well. Today when I logged in I was shocked to find I have no reputation, no badges, no question, I just found activity of those in my notification area and my profile also shows me as being a member since today.
What might have caused this? Is it a bug perhaps?
Please see attached screenshot i don't how i can show all notification from this area
