Changing Login Server Password - missing variables?

[Etara]

Hello,

I am trying to change the password on my login server account (not forum acct). I put in current password, then I put in the new password on the next line where it asks, I hit continue button. Then it says "missing variables."

I am not sure why this is happening. I still have access to everything, just want a healthy change of password to make it stronger.

Thanks!
