Today I updated WordPress for an “urgent security release,” and as usual there are unexpected side effects. For some reason now, my sliding sidebar panels no longer work. No JavaScript errors; they just don’t do anything. I blame a Scriptaculous update that is probably embedded within. I hope within the next 24 hours to diagnose and fix the problem, but for anyone (emphasis on “one”) who’s wondering why the panels aren’t working, here’s a semi-explanation.
Update (1/1/2008): File under SEU. I think the problem was simply that I needed to clear my cache. The first suspicion was aroused when I fired up MAMP, ran the site locally, and found that the sliders were working just fine. At any rate, I re-uploaded all of my theme files plus the Scriptaculous and prototype.js files, cleared my cache, and now it’s working.
