在我的标题标签之间添加了我的facebook像素代码。php主题文件，现在我的网站都搞砸了，不能正常显示。我试着删除脸书的像素代码并保存下来，但网站还是一团糟。我肯定我只删除了像素代码，但我担心我可能也删除了一小部分代码。
我想尝试还原标题的早期版本。Worpress上的php文件。
对于如何解决这一问题，也有其他想法。谢谢
这是标题。php代码-我正在尝试在标题标记之间插入Facebook像素代码。在标题标记后面还有一段Google Tag Manager代码，我没有包括这段代码，因为复制并粘贴到下面的代码时，它看起来不正确：
<!DOCTYPE html>
<html <?php language_attributes(); ?>>
<head>
<meta charset="<?php bloginfo(\'charset\'); ?>" />
<?php if (is_search()) { ?>
<meta name="robots" content="noindex, nofollow" />
<?php } ?>
<title><?php
//Yoast SEO Plugin
if (defined(\'WPSEO_VERSION\')) {
wp_title(\'\');
} else {
//The blog name.
bloginfo( \'name\' );
//Print the <title> tag based on what is being viewed.
wp_title( \'|\', true, \'left\' );
//Blog description for the home or front page.
$site_description = get_bloginfo( \'description\', \'display\' );
if ( $site_description && ( is_home() || is_front_page() ) ) {
echo " | $site_description";
}
}
