Here is my what I have put in config.js.
rotationTime: 1800000, do it automatic.
Set it to 0 (Zero), it work here.

    {
      module: 'MMM-pages',
      config: {
        rotationTime: 1800000,
        modules: [
          [ // Page 1
            'updatenotification',
            'currentweather'
          ],
          [ // Page 2
            'MMM-Telegram-Bot',
            'calendar'
          ],
          [ // Page 3
            'clock',
            'compliments'
          ],
          [ // Page 4
            'MMM-network-signal',
            'MMM-ServerStatus'
          ]
        ],
        fixed: [
         'clock',
         'compliments'
        ]
      }
    }
  ],
  useHttps: false,
  httpsPrivateKey: '',
  httpsCertificate: '',
  logLevel: [
    'INFO',
    'LOG',
    'WARN',

Made this little guide to a Led button so you can turn your
MagicMirror on and off safely, and turn it on again.
