missing subdirectories

I’ve searched the forum and docs, can’t find anything…

Seems like a simple fix that I just don’t know how to do, but I’m missing several folders that I see reference to in my site and in various docs.

I’m missing a “category” subdirectory (so there are links on my homepage that do not work). Also, when I created a static page, the entry for it appears on the home page, but when you try to click to it, I get a 404 page error. I also don’t have an “upload” directory in my wp-content folder. There may be more, but these are the things I’ve caught.

I doublechecked my permissions against those in the installation docs and they seem fine, but I think I messed something up somewhere?

Thanks for any help.
