    <p>An internal error occurred while linting the URL - What is this error?</p>
  </blockquote>
  
  <p>No other details, just this cryptic error. The linter URL that I am using is: <a href="https://developers.facebook.com/tools/debug/og/object?q=http://www.arkclothes.com/moto-retro-leather-biker-jacket/" rel="nofollow">https://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fwww.arkclothes.com%2Fmoto-retro-leather-biker-jacket%2F</a></p>
  
  <p>Does anybody know what causes this?</p>
