#200 BSD: Can't log in after upgrade to 0.89

[Anonymous]

OS: FreeBSD 4.1

After upgrading Webmin from 0.88 to 0.89 I can't log
in anymore.

When submitting the right username/password I just get
the login screen again, I don't see any error message.
Also log doesn't show any error message.

Login with non-valid username/password results as
expected in a different screen with "Login failed.
Please try again.".

I've tested this with IE & Netscape, outcome is the
same.

Upgrade on Solaris went perfect, can log in without a
problem.
