If you want FreePBX to open up in a separate window, and not have it attached to the trixbox web interface, here are the steps to do so. There is no risk at all and this will not untrix your trixbox. It will just "return" us to the olden days where trixbox and FreePBX's web interface were completely separated, and some people like me are used to this:

  1. Edit the file: /var/www/html/maint/modules/freepbx/module.xml
  2. Change <new_window>0</new_window> to <new_window>1</new_window>
  3. Save the file and login: http://trixboxIP/admin
  4. If it did not open up in its own window, do: service httpd restart
