I have taken over maintenance on a site that is using the DHVC form plugin. The site uses the plugin to display RSVP forms for events. When I try to make a new form and click “Save Form” button at the top right, nothing happens. In the console I receive the error message:

Uncaught TypeError: Cannot read property ‘models’ of undefined

Looking at the Javascript code, it appears to be failing here:

_.each(vc.shortcodes.models,function(model){}

I did some googling and I found others that have also had this issue but I have not found any solutions. Are you able to provide a solution here without access to the server? Thanks.
