Need some help with account with new version mud fish

Hello,

After i install mud fish 5.0.3 version i get this message. MUDEC_00352: [WARN] Authentication with username ‘Arentoaray’ failed - Wrong username/password. if i roll back to previous 4.6.1 version i can log in with out problems.

Weird… Did you try to change your password to a simple one and retry? However in your passowrd, do you have any special characters such as %?
