title: XAMPP, using port:81, cannot run localhost:81/mywebsite
body: <p>XAMPP's default port:80 is occupied by System.exe, so I have to switch to port:81, as this question suggested <a href="https://stackoverflow.com/questions/8103924/xampp-port-80-is-busy-easyphp-error-in-apache-configuration-file">XAMPP PORT 80 is Busy / EasyPHP error in Apache configuration file:</a> </p>
  
  <p>After this change, I can access localhost:81/xampp and localhost:81/phpMyAdmin , as well as local files, like localhost:81/wordpress/Readme.html</p>
  
  <p>However, I can not load other local directories in htdocs, can not install new wordpress site on my computer, and localhost:81/wordpress is auto referred back to localhost/wordpress , which is NOT FOUND</p>
  
  <p>Here's a list of what I tried and failed</p>
  
  <ol>
  <li><p>Change all localhost options to locahost:81, in C:\xampp\apache\conf\http.conf , in C:\xampp\xampp-control.ini , in MySQL Database, Database Tables, root User, in wordpress wp-config-sample.php , wp-config.php </p></li>
  <li><p>I load localhost:81\wordpress in Chrome and it is auto referred back to localhost\wordpress , the result is NOT FOUND.</p></li>
  </ol>
  
  <p>So I can not access to localhost:81/mywebsite because it is auto referred to the old localhost , and can not stop System.exe from using port:80. I searched almost every where, but the only solution I found is a mistyped mistake in wp-config.php - that is NOT my problem. </p>
  
  <p>Plese help.</p>
