[horde] CVS: You must configure a DataTree backend to use Shares.

[Christian Schürmann]

I did a fresh cvs install like is is suggedsted in 
http://wiki.horde.org/FC4InstallationNotes
But when I try to login and configure I just see

    A fatal error has occurred
    You must configure a DataTree backend to use Shares.
    [line 156 of /usr/share/pear/Horde/Share.php]

in the left frame. This error was reported multiple times to the list, 
but is there a _solution_? I mean, I can configure a datatree manually 
in the conf.php like this:

//$conf['datatree']['params']['driverconfig'] = 'horde';
//$conf['datatree']['driver'] = 'sql';
//$conf['sql']['params']['phptype'] = 'mysql';
//$conf['datatree']['params']['phptype'] = 'mysql';
//$conf['datatree']['params']['charset'] = 'iso-8859-1';
//$conf['sql']['params']['charset'] = 'iso-8859-1';

but the only result is, that the error msg disappers and the left frame 
stays blank. I still can't use the config interface.

Thanks,

Chris
