如何修正WordPress主题中index.php默认的id=error-page

我正在创建一个自定义WordPress主题, 并且我希望自己创建多个页面。创建第二个页面后, 在我将另一页面的模板更改为我创建的新页面之后, 主页现在显示为奇怪的中心对齐, body标记中的id = error-page。这些都不会对索引页产生影响。
我尝试将index.php复制到home.php, 但是索引页面仍然加载了奇怪的中心对齐, 并且在body标签中包含相同的id = error-page。该页面最初显示正常, 但是在为我试图创建的新页面添加页面模板后, 索引已更改。
这是我的index.php中的前几节, 显示我的代码应该正确:

< ?php get_footer(); > < !-- Background Video --> < div class="video"> < div class="overlay"> < /div> < video playsinline="playsinline" autoplay="autoplay" muted="muted" loop="loop"> < source src="http://www.srcmini.com/< ?php echo get_template_directory_uri(); ?> /videos/FFHPainVideo.mp4" type="video/mp4"/> < /video> < /div> < !-- Hero Video Text --> < div class="container h-100"> < div class="d-flex h-100 text-center align-items-center"> < div class="w-100 text-black"> < button type="button" class="btn btn-danger btn-circle btn-xl open"> < i class="fa fa-play text-white" aria-hidden="true"> < /i> < /button> < h1 class="display-3"> Family First Healthcare< /h1> < h1 class="display-3"> Pain Management< /h1> < p class="lead mb-0"> An Athens Heart Center & Specialty Clinics Affiliate< /p> < button onclick="window.location.href = 'http://www.srcmini.com/#'; " type="button" class="btn btn-danger mt-3 px-4"> Get Started Here > < /button> < /div> < /div> < /div>

我希望页面在加载时是正常的, 但是加载资源失败:服务器响应的状态也为500。(索引):1错误。

#1阅读服务器日志后, 似乎很简单。在footer.php中, 似乎我有< ?php get_ssite_url?> 而不是< php get_site_url()?> 。抱歉浪费大家的时间, 但是我很感谢查看服务器日志的建议。他们太痛苦了, 因为WordPress上托管的网站不允许FTP访问。
