@patrick I have background images linked to all of my dashboard. I wanted to bring it to your attention that none of them are loading now after uploading to 126.96.36.199 . Each dashboard has a different image, hosted on a different site, so its not a hosting issue. This is on Chrome on Windows 10, Ipad mini / safari, and Android chrome browsers.
They are still shown as configured in the dashboard settings, but dashboards are loading with black backgrounds.
