Emoncms 10.1.6-beta on Pi3 Buster, PHP 7.3, Error in nav_functions.php

Setup a new emoncms system on Pi3 wih Buster and PHP 7.3. Getting the following error when opening a dashboard:

Notice: A non well formed numeric value encountered in /var/www/html/emoncms/Lib/misc/nav_functions.php on line 366

I think @borpin might like to note this, if he hasn’t seen it earlier.

Thanks @Robert.Wall, don’t know how I missed it.


  • How did you set the Pi up?
  • Do you have any dashboards defined?
  • Did you import data?

Could you post your server information (button on admin page; just click it and paste here) please.
