Upfront editor is not loading properly

Upfront editor is not loading properly. Elements in grid only show as template code. This is happening on our demo sites and client site alwaysmarvelous.com. Where we can login and see and use the editor fine, but our client is only getting the template code.

We are seeing this on all multisites. On our demo servers we cannot edit any sites. On our live servers we can edit sites but our users are only seeing the template code.
