I purchased your Porto HTML 5 Theme. In my installation (http://www.apicslima.org/home2.html) the back to the top option is not working when clicked. It shows, but does not go back to the top of the page when clicked.
I stripped lots of the js and css files from my installation since I am not using many of your features as the theme was a bit bloated. But I left the back to the top information including the js/theme.ini.js file. I don’t know why the back to the top is not working. Please advise.
