I can't log in since more than an hour. I tried different browsers, also cleaned my cash and history (although my browsers don't keep any..)
The message I receive is "Ouptput was not in valid json format!"
Also refereshing doesn't help, even makes the things worse.. the page reloads but stays blank.. white colored. I had this problem last week also..
I saw topics for the same problem from 2011 but didn't find an answer about the problem..
Please tell me how to solve the problem..
Edited: I just read on facebook that there is some problem.. I hope after fixing it, I won't experiance this problem..
