It’s getting weirder.
After my last post I tried switching back and forth between styles in the Prefs window and suddenly Seventh Degree and Vanilla Mint became hybrids of each other. Vanilla Mint is mostly blue with a few items showing mint green (like the Preferences and Logout button backgrounds) and Seventh Degree is mostly mint green but with hints of blue — in the same places where Vanilla Mint is green. The other oddity is that the Visits Diff data now appears correctly in each, but the colors are reversed — Visits Diff is all blues in Vanilla Mint and all greens in Seventh Degree.
I put everything back the way it was — replacing the existing styles with a pristine Seventh Degree style and a pristine Vanilla Mint style, both extracted from their original zip archives.
I logged out and back in, and selected each in turn but nothing has changed. Still hybrids. I also replaced the base styles folder in Apps directory just for laughs but nothing changed.
I then tried a few other styles like Mint Chocolate, which I had never altered, and massiveblue, etc. Chocolate is messed up color-wise and the others appear as if no style is selected whatsoever.
I tried other browsers (Firefox 2, Safari 3, Camino, etc) and got more odd results, as if individual browsers interpreted the style sheet colors differently. Some browsers wouldn’t show Prefs in css at all, no matter what style was chosen.
I’m hoping Shaun has some suggestions of what went wrong and how I can fix it without reinstalling from scratch.
At least Mint itself appears to work.
