Answer 1

For those who got this error in AngularJS and not jQuery:

I got it in AngularJS v1.5.8 by trying to ng-include a type="text/ng-template" that didn't exist.

Make sure that when you use ng-include, the data for that directive points to an actual page/section. Otherwise, you probably wanted:

{{tab.content}}
