title: Cannot install Wordpress Multisite (Network) on a custom port
body: <p>I'm running a website at <code>http://localhost:8080/sitename</code>. However, when I'm trying to create a network of sites with wordpress, I'm getting the following error under <code>Tools-&gt; Network</code>:</p>
  <pre><code>ERROR: You cannot install a network of sites with your server address.
  You cannot use port numbers such as :8080.
  </code></pre>
  <p>I tried to create a virtual host and a fake domain but I can't make it work.
  How can I solve that?</p>
