Custom fields not working in upgrade to 3.1

Did you look at “Screen Options” on the top right when you are editing or creating a Post or Page? 3.1 hides some screen options by default. Just turn on the ones you want.

Thanks So much keesiemeijer – i thought i was going to have to re install an older version. Its actually a really good feature being able to turn them off, i just was not aware of it.
