title: Static Header not working: themeforest website template
body: <p>I purchased a website HTML5 template from here: <a href="http://themeforest.net/item/porto-responsive-html5-template/full_screen_preview/4106987" rel="nofollow">http://themeforest.net/item/porto-responsive-html5-template/full_screen_preview/4106987</a></p>
  
  <p>However after uploading logo.png, the static header isn't working. You can see form the demo site <a href="http://themeforest.net/item/porto-responsive-html5-template/full_screen_preview/4106987" rel="nofollow">here</a> that when you scroll, the header stays. However it seems to have glitched on my site (marketbot.net). It simply isn't responding! What code do I have to add/ replace/ remove? All I did was upload logo.png and the header is not working.</p>
