title: Why do the Vertrigo 2.21 (MySQL server do not start) do not work under Windows 7?
body: <p>It says that port 3306 might be busy - i have changed it (Settings>Components Settings) but just nothing?</p>
  
  <blockquote>
    <p>VertrigoServ → MySQL database server
    does not work correctly. Check whether
    other applications use the important
    port (3306) and terminate them.
    Moreover, check firewall settings and
    correctness the configuration files.</p>
