$resourcesDir            = dirname(__FILE__) . '/../../data/wurfl/';

$wurfl['main-file']      = $resourcesDir  . 'wurfl.xml';
$wurfl['patches']        = array($resourcesDir . 'web_browsers_patch.xml');

$cache['provider']       = 'Null';
//
$persistence['provider'] = 'File';
$persistence['dir']      = $resourcesDir . '/cache/';


$configuration['wurfl']       = $wurfl;
$configuration['persistence'] = $persistence; 
$configuration['cache']       = $cache;

if i give $cache['provider'] = null; it throws another exception . tried using $persistence['provider'] = 'file'; but no use

From what I can tell it does not look like the WURFL file is being properly loaded (perhaps the directory is not writeable) or is out of date. You most likely need to delete the persistence directory and reload the WURFL API.
