I just updated my blog, which uses a custom theme of mine, and I don't get the visual editor like I do on other newer installs of WordPress. (I've set it up for clients using Fantastico and it seems to appear there for them.) I've got a feeling there's some .php file I need to update in the themes folder, but I can't seem to find which one. And, since I crashed my blog last week, I'm skittish about hacking too much.
Any help would be appreciated.
