Hi there,
Thanks for purchasing our product. Anyway about your query it seems you’ve modified a lots & for that you’ve messed up with the structure. If you go to our demo which is this: https://demo.themeregion.com/newspress/news-details.html
You’ll notice that in the sidebar we’ve extra 2 div’s before starting the widget divs. We’re using theiastickybar to stick the sidebar & you just delete that part for which it’s not loading. Please check the demo html & you’ll be able to figure out which div. Check the screenshot: http://prntscr.com/n2ffh8
