Hey , 

You have extra div in the Footer Text Widget. Also Img element is not closed : 

Could you allow us to log in to your website backend dashboard so we can check on this for you more?. We are gonna need the username and password of admin user as well as the login url? . 

Just made the Ticket Private.

Thanks 

Hey Again,
Could you try testing for a plugin conflict. You can do this by deactivating all third party plugins, and seeing if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.

This was extra : 

This is correct code :

<div id="nav_menu-3" class="widget widget_nav_menu">
          <h4>Discover</h4>
    <div class="menu-business-demo-footer-container">
          <ul id="menu-business-demo-footer" class="menu">
              <li id="menu-item-600" class="menu-item menu-item-type-post_type menu-item-object-page current-menu-item page_item page-item-7 current_page_item menu-item-600"><a href="https://thegoodc0rners.com">Home</a></li>
            <li id="menu-item-596" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-596"><a href="https://thegoodc0rners.com/demarches">Démarches</a></li>
            <li id="menu-item-598" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-598"><a href="https://thegoodc0rners.com/articles">Articles</a>
            </li>
            <li id="menu-item-597" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-597"><a href="https://thegoodc0rners.com/contact">Contact</a>
            </li>
        </ul>
    </div>
</div>
