A couple of weeks ago, my Octoprint UI changed to a dark theme. I find it very hard to read dark red text on a dark grey background, and muddy blue buttons with black text are unreadable.
Everything I have googled talks about TouchUI (I'm not using it, it isn't installed) or Themeify (I don't use it, it's not installed).
Something must have changed but I don't recall changing anything and I thought at the time "I'll deal with it later" - a mistake, I should have addressed it while it was fresh in my mind.
The Appearance tab has no way to change the colours that I can see - the Colour drop down doesn't change anything.
How can I get back to white with black text, please?
