The customizer preview doesn't work whenever I'm trying to edit my theme.
From what I remember from when I first started customizing the theme, there would be a picture of the website, and as you ran through the options on the left-hand side, Font, Typography, etc, you could see the changes in real-time.
However, now, there is just the "X-Theme" logo and I can't see my website in the customizer. What's going on here?
Can anybody help me out?
