title: wamp server localhost not working after changing the port 80 to 8085
body: <p>I'm trying to open my Wamp server by entering this URL into my web browser:</p>
  
  <pre><code>http://localhost/
  </code></pre>
  
  <p>The browser returns a <strong>400 error</strong>, stating that the webpage is not available.</p>
  
  <p>Earlier, my Wamp server had stopped working (it was not turning green in the control panel) after I had installed <code>tomcat</code>. I found out that there was a conflict between ports with the two services, so I changed the port used by Wamp server from 80 to 8085 (8085 port is being used my tomcat).</p>
  
  <p>To change the port, I the following change to the <code>httpd.conf</code> file:</p>
  
  <pre><code>Listen 80   //changed to 8085
  ServerName localhost:8080  //changed to 8085
  </code></pre>
  
  <p>After that, the Wamp server turned green in the control panel and appeared to be working, but accessing the URL <code>http://localhost/</code> still returned the <strong>400 error</strong>.</p>
  
  <p>What is happening?</p>
