Remove both sidebars
Like the previous examples you can remove Both Sidebars elements directly from the html structure (be-left-sidebar and be-right-sidebar), additionaly you must to add the class be-nosidebar-left into the main wapper element.
<html lang="en">
<body>
<div class="be-wrapper be-nosidebar-left">
<nav class="navbar navbar-default navbar-fixed-top be-top-header">
<!-- Top bar without sidebar toggle buttons -->
</nav>
<div class="be-content">
<!-- Main content -->
</div>
</div>
</body>
</html>
