Hello, I have an error:

error:

Fatal error: [] operator not supported for strings in /home/zephyr62/www/ElderScrolls/Forum/library/KingK/BbCodeManager/BbCode/Formatter/Default.php on line 54

$user = XenForo_Model::create('XenForo_Model_User')->getUserById($idMember);
$usernameList[] = $user['username']; (line 54)

var_dump($user['username'])

$user = XenForo_Model::create('XenForo_Model_User')->getUserById($idMember);
if (is_array($user) && isset($user['username'])) {
  $usernameList[] = $user['username'];
}

When a user doesn't exist, XenForo_Model_User always returns a null value. You should always check this in your code.
