I’ve installed and activated Kepler builder and Hello Kepler Theme to give it a trial run, but I’m running into issues out of the gate.

When I click ‘Get started with Kepler Builder’, it launches what looks like a builder, but most of the UI is blank — and that’s it. I can’t proceed any further.

I’m working on:
