I just ran into a very strange issue.
Without touching any of my templates, I went to the Reading settings of WP 2.9.1, and changed the "Blog pages show at most" X posts setting. I just wanted to see how the page would look with one or two posts more showing in the list.
Refreshed my browser, and all my site layout was messed up. I figured this was a CSS issue, and looking at the code with firebug, realized that the home class was missing from the body tag. How come?
How changing the "blog pages show at most X posts" setting could cause the body home class to be dropped? Does Thematic interpreted things differently after changing that setting?
Reverting the setting didn't help. I had to edit my CSS and apply all my .home classes rules to another .blog element... which is just not right.
Can you guys think of anything? body tag home class is still missing after I had touched that setting.
