Today, I am having problems commenting on some questions and answers on Stack Overflow.
When I click "add comment", I'm not getting a response. I also checked my own profile, try to see the graph of reputation, trying to figure out whether it is because of my own system setting or website error. I'm not seeing the usual graph.
Meanwhile, usually, if I put the mouse under my username, it will show a summary of my reputation, votes cast, etc. Now if I put the mouse under my username of SO, it does not respond.
Why this is the case? Anyone experienced similar situation like me?
I'm using Google Chrome. I tried to log out, clear all cookies and passwords, logged in again, using IE to test, same problems exist.
