Trying to edit a feature request on "voices" gives a blank template page

I'm trying to edit http://stackideas.com/voices/easysocial/item/410 to change "user type" to "profile type" to be more specific. When I click on "Edit" from the dropdown menu on the right, I get this (see attachment). Not sure if it's because I've passed the time to edit the issue or not, but either way there's no error message or anything appearing.
