Without seeing what your BASE does (I expect var BASE = "{{ URL::to('/') }}"; or something similar).
Shouldn't you need to add admin to the $.post URL?

$.post( BASE + "/admin/insights/marktinfo/verwerkdata" );

Edit: Do check if BASE is http://example.com or http://example.com/. If the second:

$.post( BASE + "admin/insights/marktinfo/verwerkdata" );

My consoles says: "Failed to load resource: the server responded with a status of 500 (Internal Server Error) http://mywebite.com/admin/insights/marktinfo/verwerkdata up"

So /admin has already been added

could you post TestController?

Can you pull the 500 error from the logs?

Also, are you protecting your POST routes with the CSRF filter but not sending that with your AJAX request?

<?php
class TestController extends BaseController {
	public function index() {
		return 'test';
	}	
}

The controller does work with a normal submit button in a form...

This is what laravel logs tells me:

And no I'm not using a CSRF filter

It seems he has -> filters.php line 112 ;)

Jup you guys were right... It was because of the CSRF.. Well its weird because I'm using it so far I know.. Thanks anyways
