Config.php - datadir

[outshine]

I was having the same problem, but in my case it was because the web server was not providing me the correct path to the web site's root directory. I ended up doing this, which worked fine:

'dataDir' => $_SERVER['DOCUMENT_ROOT'] . '/documents/data',

$_SERVER['DOCUMENT_ROOT'] is PHP and returns the directory path to your web site's root directory.
