Navbar dropdown not working in IE11

Update:
no longer an issue. I have downloaded the popper from here https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.11.0/umd/popper.min.js and replace the file that came with the MDB download.

**************************************************************************************************

This is my header bit where I load all the resources:

<!-- Bootstrap core CSS -->
<link href="assets/mdb/css/bootstrap.css" rel="stylesheet">
<!-- Material Design Bootstrap -->
<link href="assets/mdb/css/mdb.min.css" rel="stylesheet">
<!-- SCRIPTS -->
 <!-- JQuery -->
 <script type="text/javascript" src="assets/mdb/js/jquery-3.1.1.min.js"></script>
 <!-- Bootstrap dropdowns -->
 <script type="text/javascript" src="assets/mdb/js/popper.min.js"></script>
 <!-- Bootstrap core JavaScript -->
 <script type="text/javascript" src="assets/mdb/js/bootstrap.min.js"></script>
 <!-- MDB core JavaScript -->
 <script type="text/javascript" src="assets/mdb/js/mdb.min.js"></script>

 

and my navbar code is this (the dropdown bit only):

<li class="nav-item dropdown">
 <a class="nav-link dropdown-toggle" id="navbarDropdownMenuLink" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">OBJECTS
 </a>
 <div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
 <a class="dropdown-item waves-effect waves-light" href="/categories">CATEGORIES</a>
 <a class="dropdown-item waves-effect waves-light" href="/subjects">SUBJECTS</a>
 <a class="dropdown-item waves-effect waves-light" href="/modules">MODULES</a>
 <a class="dropdown-item waves-effect waves-light" href="/packages">PACKAGES</a>
 </div>
 </li>

Hi Piotr, Thanks for noting the IE navbar dropdown issue. Popper.js, just as the MDB itself and, as a matter of fact, all the other web technologies involved, constantly develops. It means that our small team tirelessly seeks feedback from the community to point out issues to be resolved, implementation bloopers to get rid of and functionalities to be added in the future. Long story short – we’re happy to hear the issue got resolved; the knowledge of how it got done will be used to improve MDB. The popper.min.js included in our package shall be updated shortly, thank you much for your patience. Cheers, Kuba
