When I last dealt with Wordpress, it seemed like enabling Caching was pretty straightforward. Maybe I'm remembering wrong?
Hmm, I don't know of any way to enable caching in Wordpress itself. I found a plugin for it called wp-super-cache or something like that, but it requires some configuration (a couple of Apache modules, like mod_rewrite, among other things -- I typically disable all modules) unless I need them.
Maybe there's an easier way that I just didn't know about, though. I'll have to take a look.
