Argument 'MainCtrl' is not a function, got undefined?

Question

I get this error:

Uncaught ReferenceError: MainCtrl is not defined, Argument 'MainCtrl' is not a function, got undefined

In plnkr it works okey but in my project not.

I have this in layout:

 <li ng-click="changeActiveMenu('Settings');"><a href="../Account/#/PersonalInfo">@Translate("MY_ACCOUNT")</a></li>

Seems like you did not included your MainCtrl in index.html file like this

<script src="scripts/controllers/main.js"></script>

ok then, did you added your MainCtrl in your angular module ? – Muhammad Suleman Jun 24 '15 at 07:57
var app = angular.module('Online', []); app.controller('MainCtrl', ['$scope', 'ActivityService', function ($scope, activityService) {....}... yes i am – None Jun 24 '15 at 08:00

It is already answered here. In angular 1.3.x versions, you need to register the controller using module.controller syntax. Like

angular.module('plunker', []).controller('MainCtrl', ['$scope', 'ActivityService', function ($scope, activityService) { 

//Code

}])

Possibly there may be another reason. You're angular script is not loading on the dom. Please use

<script data-require="angular.js@1.3.x" src="//code.angularjs.org/1.3.16/angular.js" data-semver="1.3.16"></script>

OR

<script src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.3.16/angular.js"></script>

Without any http or https protocol.
