UP ! Any plugin I could use ? (The ones I found were only for the category widgets on the viewable part of the blog, but nothing about the admin part).
My mistake, “delete” only delete the value and not the custom field itself, but anyway Author can still “Add another custom field” and Edit it’s name, and I’d like to disable this.
Had to say thanks to alchymyth, was getting on my nerves and then it worked like a charm ! 🙂
