I've got two websites I'm developing that I can not access the "Add New Custom Field".
I can pick from a list of things already there, but when I click the button to "Add Custom Field" it opens up the place where you SHOULD be able to type in the new field but instead it has no form fields to type into.
It looks just like this http://ratest9.com/custom-fields.jpg
On other sites I have when you click that button you get someplace to type.
I've disabled all plugins and changed to either the 2011 or 2012 themes.
