First of all, I have purchased the MDB PRO license, and I am not a free user. Can you please advise how to reach the premium support ?

The issue can be replicated by replacing the index.html file with the attachment in the MDB RPO product.

It seems that I am not able to attach a whole .html file, the error seems to appear somewhere :

<!--Main Navigation-->


<!-- Navbar -->
<nav class="navbar navbar-expand-lg navbar-dark fixed-top scrolling-navbar">
  <div class="container">
    <img src="img/libertyglobal-logo.png" class="img-fluid" alt="libertyglobal-logo" style="width: 30px">

    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent-7"
      aria-controls="navbarSupportedContent-7" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarSupportedContent-7">
      <ul class="navbar-nav mr-auto">
        <li class="nav-item">
          <a class="nav-link" href="#">Looking Glass</a>
        </li>
      </ul>
    </div>
  </div>
</nav>
<!-- Navbar -->


<div class="container">

  <!--Section: Apps-->
  <section>

    <!--Grid row-->
    <div class="row">

Expected behavior

Do not display the blank area (denoted with a red rectangle in the attached screenshot).

Actual behavior

Make the denoted with a red rectangle in the attached screenshot area disappear.

Resources (screenshots, code snippets etc.)

The HTML source was derived from the profile-page.html from MDB PRO and it's a striped down version of it.
