title: XAMPP MySQL shuts down unexpectedly
body: <p>XAMPP MySQL shuts down unexpectedly. I was trying to enable the configuration storage settings earlier, turned my PC off, and returned to this.  I have uninstalled and reinstalled XAMPP within the past couple of days, changed port numbers to apache and setup a password. </p>
  
  <p>I've deleted the ibdata1, ib_logfile0, and the ib_logfile1 files, and changes the port numbers to the my.ini and php.ini files.</p>
  
  <p>Help would be appreciated.  </p>
