Over the past couple hours, the forum theme changes on it’s own. Is Discourse working on something? I use the light theme and its gone back and forth between light and gray.

I had the same issue. The dark theme I was using all of a sudden didnt work anymore. Lokked terrible, with a log of gray and little contrast. pretty much like your screenshot.

I had to select Horizon / Horizon Dark to get back to a dark theme.
