Using Streamline child theme:
I did check the W3C
Markup Validation Service on ip-192.com
and get 2 errors.
Error Line 243, Column 6: end tag for element "div" which is not open
</div> <div id="footer-widgeted">
This Error belongs to an empty sidebar-bottom-left div, which is correct defined.
Error Line 280, Column 6: end tag for element "div" which is not open
This Error closes a widget_nav_menu.
I see unclosed </body> and </html> tags at the bottom of the page.
This problem happens at Streamline child home pages with different customizations.
Any hint how I can solve this would be very much appreciated.
