Hoping someone might have a solution for this problem that has only started happening since last night when we updated Discourse to 2026.4.0-latest (e4ab7a2cc9)
We use white font for all of our category badges and they display correctly when you’re at the top of a topic
Second tip is to mention what theme you are using. I think the issue will be specific to that theme, since the screenshot isn’t showing the default tag look.
Third tip is to check via the inspector what is happening and post a screenshot of it here.
Using the inspector, this seems to be causing the problem, because when I untick the top line, the font colour then reverts to the correct colour (white).
