[horde] problem with password

[alois blasbichler]

hello,
i use horde 2.1 with imp3.1 and openldap 2.1.4

all works fine, i have only a smal problem with the password-tool
its working and i can change the password in ldap

the problem is that the site have strange settings: the background is white,
not very nice.
When i cancel the last 2 lines in conf.php, then the settings are the default

somebody can help ?
