You need to fix your 'home' path then.  'all_user' is a relative path. 
  You probably are looking for a static path instead such as 
'/var/teclabs/vfs/all_user'.

With the current CVS version I cannot change [1]the directory. backend config:



$backends['global'] = array(

     'name' => 'Virtual Directories',

     'driver' => 'file',

     'preferred' => '',

     'params' => array(

         'vfsroot' => '/var/teclabs/vfs',

         'home' => 'all_user'

     ),

     'attributes' => array('type', 'name', 'download', 'modified', 'size')

);



When I enter the file manager, I can see the content of 
/var/teclabs/vfs/all_user, but the "path" shoes [Root]/all_user// (the 
last two "/" have not been there in the previous version. When I try 
to open /var/teclabs/vfs/all_user/test, I get an error:



Permission denied to folder "all_user///all_user//test": Not a directory



[1]ok, sometimes it is working, sometimes not. But it's more not 
working, then it is working.
