Hello there. I have installed the theme and gotten the website up and running fairly well. However, I want to replace all of the stock photographs with my own. However, once I’m customizing when I click the buttons that say “Select Image” nothing happens. This happens on all pages/sections. The screen doesn’t show anything is loading, it’s just as if the button click doesn’t do anything. I’ve tried both in Firefox and Chrome so far and have had no luck. Any advice?
