Can someone tell me why contentarea isn't working?

[zushiba]

Code: Select all

#Content Areas
contentareas:
    name: ContentAreas
    singular_name: ContentArea
    fields:
        title:
            type: text
            class: large
        body:
            type: html
            height: 300px
    showondashboard: true


It was working fine, then suddenly disappeared from the Content dropdown, the table still exists in the database with my content intact, I'm just unable to edit or even see it.
