i get a message first about $cookie_domain then config.php

so I realized on my host that Fck 2.6.5 gets an error message in Drupal's Status Reports about needing to set $cookie_domain since i have quick uploads and built-in browsing enabled...
so i set that, then the next message is:

You are using a feature that requires manual integration into config.php (either built-in filebrowser or quick uploads are enabled in the Advanced profile). Read instructions about enabling built-in file browser and add "require_once ..." statement in editor/filemanager/connectors/php/config.php.

so i read up and change it to false and also set where browsing can start from:
$Config['Enabled'] = true ;
$Config['UserFilesPath'] = '/sites/default/files/' ;

I clear cache and
still get that message...
Wondering what am I doing wrong?
Thanks!
