Hello!
I was using pihole and saw there was an update, updated to the latest version and everything is fine but I am pretty sure the ui theme has changed. I don't remember changing any settings. I personally like the old theme much better but I didn't see any changes about the themes in the changelog. I was wondering if the theme actually changed of if something else is causing it. I have only noticed the theme change in the Query Log page if that matters.
Thanks!
