I've included toaster.css, toaster.js and jquery like that:
<script src="Scripts/jquery-2.1.4.js"></script>
<script src="Scripts/toaster.js"></script>
<link rel="stylesheet" type="text/css" href="QtApp/Notifications/toaster.css" />
and i am sure that the paths are correct. But when I try to call toaster.pop(..) or toaster.error(..) the respective functions are called and executed but no popup is shown. Any idea why that happens?
