hi raden,

Did you customize any code? If no then first deactivate all the plugins that you have installed in the dashboard. The margin may come from plugins. This unwanted div is available in your site.
<div id="undefined-sticky-wrapper" class="sticky-wrapper" style="height: 101px; margin-bottom: 101px;"> So deactivate all the plugins and test whether same problem exists or not.

Thank you!
