JQuery via the .info file isn't working I'm using/experimenting with Zen on my drupal site, and have just inserted a js file named alert.js into my theme's js folder.
The file has the following code:

  (function ($){
Drupal.behaviors.kiwiAlert = {
  attach: function(){
    alert('Hello World');
   }
 };
})(jQuery);


I followed up by making the necessary changes in my .info file, by inserting the following snippet:

 scripts[] = js/alert.js


Since my site is in development mode I've set the cache to be cleared/theme registry to be rebuilt upon each page load, but just in case I cleared my cache again.
And nothing, the alert message doesn't show, why is this not working??

PS: I also tried the following code in the js file, in the same context, but to no avail :C

 alert("Hello World!!");


Any and all answers will be much appreciated :)
Answered in comments, but just moving the answer here for posterity's sake.

The theme was loading the .js file, but the permissions were restricted, so the server was returning a 403 error. Changing the permissions fixed the issue.
