We recently upgraded our EPi 10.9 project to Epi 11 latest using the Nuget packages and datbase update. Most of our site looks great locally, but Epi Forms doesn't work at all. Whenver you click any button, you get this error:

We've tried almost everything. Lots of checking the web.config and the like. No dice.

Has anybody else gotten this?

Look like some of your resources are not loaded. Do you see any request return error (http code 500 for ex)? Or did you do a custom view template (ascx files)?
