@asif: I am facing login problem from today. I am giving my local username and password to login but it say... Login failed. Please enter valid username and password (both are case-sensitive). This user is not a valid user. This all happened because I clicked forgot password and logged in with temporary access key. And after providing the right username and password it says. Login failed. I am unable, not only I, everyone is facing problem in changing password. As after clicking authentication setting it says... 500 Server Error
sorry, system error system error log is recorded, error will be fixed as soon as possible. please report the error to the site administrator if you wish.
