我在一个wordpress网站上工作，它突然停止了工作。到处都是空白页。这是一个全新的网站，只有我对其进行了更改。问题发生在我构建自定义模板时。这是我尝试用清除缓存时的错误消息wp cache flush
PHP Warning: mysqli_real_connect(): (HY000/2002): No such file or directory in /Users/Jillian/sites/wp2/site/web/wp/wp-includes/wp-db.php on line 1538

也许比我更有wordpress经验的人可以解释这个问题？
罪魁祸首如下：
自定义模板：测试模板
<!-- http://wp2.dev/44-2/ -->
<?php /* Template Name: Test Template */
function mypage_head() {
echo \'<link rel="stylesheet" type="text/css" href="\'.get_bloginfo(\'stylesheet_directory\').\'/sass/style.css">\'."\\n"
}
add_action(\'wp_head\', \'mypage_head\');
get_header();
$page = get_post_meta(44);
// Dsiplay the page title (without >> in front)
$header = $page[\'header\'][0];
$subheader = $page[\'subheader\'][0];
?>
<section class="span12" id="HomeHeader">
<h1><?php echo $header; ?></h1>
<div class="subtext"><?php echo $subheader; ?></div>

<section class="span12" id="HomeProjects">

<?php endif; ?>
<div class="subtext category"><?php echo $category; ?></div>
<h2><?php $title; ?></h2>
<div class="content"><?php echo $description; ?></div>
<a href="<?php echo $link; ?>" class="read-more"><?php echo $link_title; ?></a>
</div>
<?php
}
?>
</section>
<section class="span12" id="HomeClients">
<h1>Clients</h1>
<?php
//Display all clients
$args = array(\'post_type\' => \'client\');
$posts = get_posts($args);
foreach($posts as $post) {
// $title = the_title();
$icon = get_field(\'icon\');

?>
</section>
<section class="span12" id="HomeNews">
<?php
// Display news section
$title = $page[\'title\'][0];
$content = $page[\'content\'][0];
$news_link = $page[\'news_link\'][0];
$news_link_title = $page[\'news_link_title\'][0];
$args = array(\'post_type\' => \'post\'); // Query just regular posts
$posts = get_posts($args);
?>
<div class="posts">
<div class="subtext">Latest</div>
<?php
foreach($posts as $post) {
// setup_postdata($post);
$date = date_format(date_create($post->post_date), \'jS F Y\');
?>
<div class="date"><?php echo $date; ?></div>
<div class="content"><?php $post->post_content; ?></div>
<?php
}
?>
</div>
<div class="news">
<h2><?php echo $title ?></h2>
<div class="content"><?php echo $content ?></div>
<div class="btn news-link"><a href="<?php echo $news_link ?>"><?php echo $news_link_title ?></a></div>

</section>
<section class="span12" id="HomeCTA">

<div><?php echo $page[\'phone\'][0]; ?></div>
<div><?php echo $page[\'address\'][0]; ?></div>
</div>
</section>
我还添加了一些变量和样式
_elements.scss@import url(\'https://fonts.googleapis.com/css?family=Lato|Lora:700i|Work+Sans:800\');
$header-gray: #5d6771;
$subtext-blue: #5ac3b6;
html {
box-sizing: border-box;
}
*,
*:before,
*:after { /* Inherit box-sizing to make it easier to change the property for components that leverage other behavior; see http://css-tricks.com/inheriting-box-sizing-probably-slightly-better-best-practice/ */
box-sizing: inherit;
}
body {
background: $color__background-body; /* Fallback for when there is no custom background color defined. */
}
blockquote, q {
quotes: "" "";
&:before,
&:after {
content: "";
}
}
hr {
background-color: $color__background-hr;
border: 0;
height: 1px;
margin-bottom: 1.5em;
}
@import "lists";
img {
height: auto; /* Make sure images are scaled correctly. */
max-width: 100%; /* Adhere to container width. */
}
figure {
margin: 1em 0; /* Extra wide images within figure tags don\'t overflow the content area. */
}
.container {
width: 100%;
}
h1 {
color: $header-gray;
font: 800 51px/52px Work Sans, sans-serif;
font-weight: 900;
}
.subtext {
color: $subtext-blue;
font: italic bold 21px/25px \'Lora\', serif;
}
@import "tables";
谢谢！

您收到的错误消息告诉您，您的数据库设置无法创建连接。您是否更改了wp配置。php？先检查一下。然后检查数据库服务器是否正在运行。
Error: Error establishing a database connection. This either means that the username and password information in your `wp-config.php` file is incorrect or we can’t contact the database server at `localhost`. This could mean your host’s database server is down.
