Login issue

[Cdmar]

Hello,

I have ispCp 1.0.5 installed and running on a Debian 5 system.
I noticed that there is a problem with logging-in.

If I enter everything correctly (login & password) right at the first time, it goes through just fine. However, if I will provide a wrong password at first login attempt, it will not allow me to log-in anymore after the first attempt, even entering correct password many times afterwards. It just reloads the page and returns me back to log-in. So to tell it in brief, I have to enter
correct data right from the start to log-in, if I will somehow provide it wrong, it will not allow me to log-in anymore after the first login attempt. I already tried disabling brute-force detection or block-time between logins, it didn't help. I don't know what is the issue.

I would be glad if someone would take time to help me looking into and solving this technical problem.

Thanks in advance.
