That week in 2019 when my forum theme broke for 3 days straight
I was running a vintage gaming forum back then (maybe 200 members, nothing huge) and I spent a whole weekend trying to fix a CSS conflict that made the entire site render as a solid white page. Turned out it was one missing semicolon in a custom theme file, something I'd overlooked after like 8 hours of debugging. Has anyone else had a layout bug that took way too long to find because of one dumb typo?
