If your using PHP 5.3 still, like we are (don't ask), then you'll need to change the new short code used for an array assignment on line 22 of WPSimpleNonce.php.
Change:
return ['name'=>$name,'value'=>$nonce];
TO:
return array ("name" => $name, "value" => $nonce,);

See http://php.net/manual/en/language.types.array.php "Example #1 A simple array". As of PHP 5.4 you can also use the short array syntax, which replaces array() with [].
