For some reason, all of your “Settings” are returning a 404 error.

Is it possible that a plugin may have modified your .htaccess file, and it’s routing anything with “settings” in the URL someplace else?

Do you mind posting your .htaccess contents here for me?

If you are 100% positive the files are in the right places, the next thing to try is to systematically deactivate plugins one by one, and search for a conflict of some kind.
