Basic UI not showing some icons in browser

I’ve got a OpenHABian running on a Raspberry Pi 3, and another installation of OpenHAB running on my Macbook using Docker (for local dev/testing).

On both systems, some icons in the basic UI are not showing on desktop browsers (I’ve tried Safari, Firefox and Chrome on Mac). - However, the icons are visible just fine in Safari on my iPhone.

Since this is happening on both installations, I guess there is some weird little bug or setting I’ve missed?

(See screenshot, where squares are shown instead of icons)

Weird, in my BasicUI the icons are in front of the items, not at the end…

Did you check this documentation to check if your sitemap configuration is in line with the docs:

http://docs.openhab.org/configuration/items.html#icons

The squares in the screenshot are the arrows to move to the next page. - In the header the weird squarish icon is supposed to be the Home (house) icon.

The screenshot is from the demo setup, so should work out of the box.

I hardly use the basic UI, but when I do I indeed notice that my custom icons do not show up. Isn’t that because basic UI expects svg? Unless you configure them for bitmap (do that in the PaperUI under configuration)
