title: Laravel Valet replacing public sites with 404 Not Found
body: <p>I'm learning Laravel, and I successfully installed Valet. Did some basic development. Then moved on to other things totally unrelated. About a week later (today) I visited two sites (in Chrome and Safari Mac):</p>
  
  <ul>
  <li>postmarkapp.com</li>
  <li>getsatisfaction.com/activeinbox</li>
  </ul>
  
  <p>And I get "Valet - Page Not Found".</p>
  
  <p>I do not get this issue any other website I visit. And I've never seen something selectively take over a site like this. It's obviously related to my local configuration but because I'm new to Valet I have no idea where to start with this.</p>
  
  <ul>
  <li>What is happening?</li>
  <li>How is this possible?</li>
  <li>How do I resolve this?</li>
  </ul>
