I am developing a wordpress theme and I think at some point I messed something up pretty badly in the wordpress system because nothing works anymore.
I have tried several different themes, mine and the ones that come with wordpress. I have removed all plugins. I even reinstalled all of the wordpress files through ftp. No matter what I try I always get 404 errors when I try to view a page or a post or anything other than the actual home page. I have not anything fancy with the urls. For example, I am trying to view the default "Hello World!" post simply using the /1. I haven't added an .htaccess file. All of the back end stuff is working fine. I don't know how this makes sense, and I don't know where to go next while trying to debug this.
