Since a few hours I only see a black browser window when accessing HABpanel. No panels, no widgets and even no controls. I tried different browsers and devices. An uninstall and reinstall via the PaperUI didn’t work either. When I use the static URL (http://openhab.fritz.box:8080/static/habpanel/index.html#/settings) instead of the dynamic (http://openhab.fritz.box:8080/habpanel/index.html#/) I get a non up-to-date version, but all looks good.
Yesterday I switched to the new snapshot repository (as described here Replacement of the Apt Snapshot Repository) and the latest build, but all worked fine.
I have exports of my panels and controls, but I can’t import anything, because there are no controls at all.
