WordPress Codebird不起作用（白色屏幕）

Question

我尝试为最近的推文小部件实现Codebird。每次我将其添加到我的 functions.php 时，我都会看到一个白屏（我认为500内部服务器错误）。我不知道Codebird真的很好，所以我希望有人能帮助我。

$options = get_option('wordpress_theme_options');

add_action( 'init', 'my_twitter_api' );
function my_twitter_api() {
    global $cb;
    $consumer_key = $options['consumer_key'];
    $consumer_secret = $options['consumer_secret'];
    $access_token = $options['access_token'];
    $access_secret = $options['access_secret'];

    include("codebird.php");
    Codebird::setConsumerKey( $consumer_key, $consumer_secret );
    $cb = Codebird::getInstance();
    $cb->setToken( $access_token, $access_secret );
}
