{Plugin : Facebook} Cant make a new post..

Heya Everyone,
I installed Facebook’s brand new plugin at https://www.commenti.org before a few days. Till now, everything was working fine, but now its giving some error like Fatal error: Wrong parameters for Exception([string $exception [, long $code ]]) in /home/content/01/6060501/html/wp-content/plugins/facebook/includes/facebook-php-sdk/base_facebook.php on line 54 and when i checked the php file its like
/**
* Make a new API Exception with the given result.
*
* @param array $result The result from the API server
*/
public function __construct($result) {
$this->result = $result;

$code = isset($result[‘error_code’]) ? $result[‘error_code’] : 0;

if (isset($result[‘error_description’])) {
// OAuth 2.0 Draft 10 style
$msg = $result[‘error_description’];
} else if (isset($result[‘error’]) && is_array($result[‘error’])) {
// OAuth 2.0 Draft 00 style
$msg = $result[‘error’][‘message’];
} else if (isset($result[‘error_msg’])) {
// Rest server style
$msg = $result[‘error_msg’];
} else {
$msg = ‘Unknown Error. Check getResult()’;
}

parent::__construct($msg, $code); //line 54
}

Anyone there to help??
