The full message is 
        "
        Fatal error: Perms::getPermissions() [<a
        href='function.getPermissions'>function.getPermissions</a>]: The
        script
        tried to execute a method or access a property of an incomplete
        object.
        Please ensure that the class definition
        &quot;DataTreeObject_Permission&quot; of the object you are
        trying to
        operate on was loaded _before_ unserialize() gets called or
        provide a

        But there was a new install on this shared server of another
        clients
        horde, in a different folder and different DB and different URL.
        Maybe though they are sharing a common 'cache'?
        
        I tried a new DB and the same problem.
        New install w/ the latest horde 
        Horde Groupware Webmail Edition 1.2
        I was running 1.1 before this.
        
        I want to make sure not to mess with the clients installation,
        fortunately the one that is broken is our own.
        
        It is php 5.1 and mysql 5.02
        
        Here is the conf file

        I did search the lists for some key words from the error. But if
        it is a
        a php sessions I was not sure how to wipe it.
        I tried other computers too.
        I read also restarting the apache should help but how do I
        prevent this from happening to the other installs?
        Thanks
