How to fix “id=error-page” default on index.php in a WordPress theme

Question

I am creating a custom WordPress theme and I want to have multiple pages that I create myself. After creating a second page, the home page now displays in a strange center alignment with id=error-page in the body tag after I changed the other page's template to the new page I created. None of this should of had an affect on the index page.

I have tried copying my index.php into home.php, but the index page still loads with the weird center alignment and contains the same id=error-page in the body tag. The page displayed fine originally, but after adding a page template for a new page I was trying to create, the index has changed.

Here is the first few sections in my index.php to show my code should be correct:

    <?php get_footer(); >

    <!-- Background Video -->
    <div class="video">
      <div class="overlay"></div>
        <video playsinline="playsinline" autoplay="autoplay" muted="muted" loop="loop">
          <source src="<?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 = '#'; " type="button" class="btn btn-danger mt-3 px-4">Get Started Here ></button>
        </div>
      </div>
    </div>

I expect the page to be normal when I load it, but I get a Failed to load resource: the server responded with a status of 500. (index):1 error as well.

Here are the most recent server logs:

Answer 1

Most likely the error is caused by this:

<?php get_footer(); >

Change to

<?php get_footer(); ?>

If that's not it, add the error message from your server error logs to give us more information.

Answer 2

After reading the server logs, it seems it was something simple. In footer.php , it seems I had <?php get_ssite_url?> instead of <php get_site_url()?> . Sorry to waste everyones time, but I appreciate the advice to look at the server logs. They are a pain to get too because sites hosted on WordPress don't allow FTP access.
