title: Wordpress featured images and media library thumbnail no longer displays
body: <p>I have a WordPress blog that is on a VPS. Everything has been working fine until today when I realised that my featured images are no longer displaying. I logged in to my dashboard, media library, and all the image thumbnails are no longer displaying properly.</p>
  
  <p>Before this time, I had a little issue with my caching plugin (W3Total Cache), so I deactivated it, and my site continued to function normally. But now, no featured image is displayed all through the site. What amazes me is that inline images in a post are still displaying in the site. <a href="http://www.loggtv.tv/2015/11/24/whao-ty-bello-chops-off-her-signature-afro-peep-her-new-look/" rel="nofollow">See example</a>.</p>
  
  <p>Now my site's <a href="http://www.loggtv.tv" rel="nofollow">homepage</a> is just blank, because no featured images are displayed. As of today, images which I attached in the post are just seen as links, but if the link is clicked, it redirects to the image. Here are some of the things I've tried so far:</p>
  
  <ul>
  <li>I've run <code>df -h</code> ssh command to verify if my diskpace is full.</li>
  <li>I've restarted <code>mysql</code> server several times.</li>
  <li>I've manually downloaded wordpress .zip file, and upload to the site.</li>
  <li>I've automatically <code>reinstall</code> wordpress using <code>http://www.example.com/wp-admin/update-core.php</code>.</li>
  <li>I've switched to a default theme.</li>
  <li>I've tried some of the resources similar to this question here, but none of the proffered solutions resolved my issue.</li>
  <li>My permission settings for all the sub-directories under <code>wp-content</code> is <code>755</code>. I have also tried changing them to <code>775</code> and <code>777</code>.
  *. I've used the Regenerate Thumbnails plugin to try to regenerate the thumbnails, but it returned an error <code>The error message was: The originally uploaded image file cannot be found at</code>, but when I view the image directly from my browser, it returns the image.</li>
  <li>I've also used the <strong>WP Original Media Path</strong> plugin to try and restore the media path (if it was messed up), but to no avail.</li>
  <li>I've deactivated all plugins too.</li>
  <li>I just checked my <code>wp_postmeta</code> table in my DB and it returned this error <code>wp_postmeta table is marked as crashed</code></li>
  </ul>
  
  <p>How do I rectify this issue?</p>
