e is not a function

Hi there,

I am getting the below error whenever I try to change a background image, or avatar on the teams page or user page.

Uncaught TypeError: e is not a function
    at N.d.resetDisplays (media-views.min.js:1)
    at N.d.initialize (media-views.min.js:1)
    at N.d.b.Model (backbone.min.js:1)
    at N.d.constructor (media-views.min.js:1)
    at new N.d (backbone.min.js:1)
    at N.d.createStates (media-views.min.js:1)

    at N.d.b.View (backbone.min.js:1)
    at N.d.constructor (wp-backbone.min.js:1)

Any idea? Happens on https://www.reaperscape.net/members/okaeri-admin/ for example.
