MCServer WebAdmin - bad username or password

[asker]

Hello,

i installed MCServer and changed the webadmin.ini to

Code:

; This file controls the webadmin feature of MCServer
; Username format: [User:*username*]
; Password format: Password=*password*; for example:
; [User:test]
; Password=test123

Then i tried to browse to the webadmin: http://192.168.1.83:8080/webadmin/
But every time it asks me for username and passwort. it does not accept the user and pw above and says MCServer WebAdmin - bad username or password. I restarted the server and the raspberry and so on, but it doesn't work.
can you say me what i'm doing wrong?
