After updating to Emoncms Version low-write 9.8.15 | 2017.11.18 Local EmonCMS with EmonBase no more values (widget) are visible on dashboard.
Emoncms - dashboard view “http://emonpi/emoncms/MyUserName”
Thanks for reporting, I have been unable to replicate the issue the widget values are displayed for me on my dashboard running the latest version. Could you double check that your feeds are public for the widget? Are there any errors showing in your browser Developer Console?
